• Windows 7 Media Center: sometimes no sound on a TV channel

  - by torbengb

  Problem Sometimes, recorded TV shows have no sound. This is of course very annoying because the recorded show is worthless. Also, when switching channels while watching live TV, sometimes a channel has no sound. This is always solved by switching channel again and then back (most often, once will do the trick). Media Center doesn't do this trick by itself when recording of course, so that's the bigger issue - but the cause is certainly the same. Details The computer is running a newly installed Windows 7 and Windows Media Center. It has 2 different tuner-cards installed. Both are installed with signed and up-to-date Win7 drivers and appear OK in Device Manager. Both tuners get the same antenna signal, from a split cable from the wall. The cable delivers analog cable TV (40+ channels) and digital cable TV (4 channels) at the same time. Both tuners have been configured to receive both analog and digital channels. This only happens with analog channels. How can I fix the no-sound problem? Update: I've now spent some time with the computer to try and pinpoint the problem, but I've had little success so far: I flipped through the channels until one didn't have sound, then I disconnected the antenna cable from one of the tuners. It was the right one because then the video also went away. I flipped lots more channels to see if the other card also would come up mute once but I never had a channel without sound. It might still be possible, I don't know. Then I disconnected the "good" tuner and connected the "bad" tuner and again flipped lots of channels but again I never had a channel without sound. It seems to me that the problem is erratic. It happens on any channel, and I haven't ruled out yet that it only happens on one tuner.

• Frequent connection drops when playing online games (StarCraft 2, Battlefield 3) and behind NAT - how to diagnose?

  - by Moshev

  I am having some trouble with (I suspect) my wireless router. It's connected to the internet with a regular lan cable and has a static, public IP address. Our two home PCs connect to the router with regular lan cables, plus there's a laptop which connects over wifi. diagram: Internet | | <- isp-supplied cat5 ethernet cable | D-Link D300 ...wifi... laptop / \ / <- cable -> \ PC1 PC2 The PCs and laptop are behind NAT and share the router's public IP. The router is a D-Link D300. PC1 is used for online gaming and I'm experiencing frequent "connection dropped" errors when playing Battlefield 3, StarCraft 2 and the Diablo 3 beta; but not with TeamFortress 2 or the Tribes Ascend beta. The issue goes away when I remove the router and connect PC1 directly to the ISP's cable. I have also tried disconnecting PC2 and the laptop, leaving PC1 as the only machine connected to the router - doesn't help. How can I diagnose what precisely the issue is?

• How do I automatically download files to a Kindle 2 whenever its USB connection is plugged into a Windows 7 machine?

  - by Bob Cross

  The inspiration of this question is the Gadget Lab article How To Make Your Kindle Into an Automatic Instapaper. In that article, they describe an implementation of an Automator workflow that: Detects the connection of a portable disk (which the workflow assumes is the Kindle 2). Downloads the Instapaper mobi file containing the text version of the articles marked for "Read Later" to the computer. Downloads the mobi file from the computer to the Kindle 2. All of this is straightforward in terms of functionality but it is not immediately obvious how to do step 1 on a Windows box. Is the Task Scheduler the first step? If so, which event should be the trigger for the rest of the task?

• Need USB drivers for Nexus One and Mac Snow Leopard?

  - by melling

  I got a AT&T compatible Nexus One that I'm trying to connect to my Mac Book Pro (Snow Leopard) for development. When I do an adb devices, it doesn't appear, and I can't do an adb install either. Until today, I've been using a G1 and I haven't had any issues. I haven't placed a SIM in the phone yet, but I don't think that should matter.

• if i have two external hard drives connected to my computer by USB (2.0 i think) will they load with consistent letters?

  - by Bec

  (I'm using windows-7 and the hard drives are western digital with whatever formatting they came with from the factory) i'm thinking of setting up two different back-ups one through windows and one with the software that came with the drive (because windows gives me a system image but isn't very user-friendly for my files) but will my computer get confused and load them as different letters each time?

• Dual LAN Printing

  - by Christopher

  I want to use Ubuntu 10.10 Server in a classroom, a computer lab whose bandwidth is provided by a local cable ISP. That's no problem, though the school network has an IP printer that I want to use. I cannot reach the printer through the cable Internet. But, I have two network cards. How is it possible to use both networks at once? eth0 (static 192.168.1.254) is plugged into a four-port router, 192.168.1.1. On the public side of the four-port router is Internet provided by the cable company. I also have the classroom workstations plugged into a switch. The switch is plugged into the four-port router. The whole classroom is wired into the cable Internet. The other NIC, eth1, could it be plugged into an Ethernet jack in the wall? It uses the school network, and I might receive by DHCP an IP address like 10.140.10.100, with the printer on maybe 10.120.50.10. I was thinking about installing the printer on the server so that it could be shared with the workstations. But how does this work? Can I just plug eth1 into the school network and access both LANs? Thanks for any insight, Chris

• Ubuntu 12.04 Freezes w/ Ethernet Unplugged + Wireless Drops (Acer Aspire 5516)

  - by Grand Master T

  Ubuntu 12.04-12.10 32/64 freezes or won't boot if the Ethernet cable is unplugged and will not hold a wireless connection. Here is my scenario... Laptop: Acer Aspire 5516 Wireless card: Broadcom BCM4312 Ubuntu 12.04 32/64 Issues Unity 3d won't load without the Ethernet cable plugged in. If I let it load with Ethernet plugged in, it will freeze once I disconnect the cable. Unity 2d will load without the Ethernet cable plugged. In Unity 2d, wireless cannot hold a connection. I can connect to a Wireless network, but when I try to use it (i.e. open a browser), it disconnects. I can reconnect by disabling wireless (uncheck Enable Wireless), re-enable wireless, and reconnect. But, it will disconnect again once I start using it. Ubuntu 12.10 Issues Since 12.10 only gives me the option to load 3d (I assume), I experience the same thing as the first issue in 12.04. Attempted Solutions Enable networking/LAN in BIOS Set LAN first in boot priority in BIOS Remove STA wireless driver (bcmwl-kernel-source) and install b43 low power driver (firmware-b43-lpphy-installer). Remove default Network Manager and install Wicd. So far, I have had no luck with fixing this issue. Does anyone have any further suggestions?

• Move Files from a Failing PC with an Ubuntu Live CD

  - by Trevor Bekolay

  You’ve loaded the Ubuntu Live CD to salvage files from a failing system, but where do you store the recovered files? We’ll show you how to store them on external drives, drives on the same PC, a Windows home network, and other locations. We’ve shown you how to recover data like a forensics expert, but you can’t store recovered files back on your failed hard drive! There are lots of ways to transfer the files you access from an Ubuntu Live CD to a place that a stable Windows machine can access them. We’ll go through several methods, starting each section from the Ubuntu desktop – if you don’t yet have an Ubuntu Live CD, follow our guide to creating a bootable USB flash drive, and then our instructions for booting into Ubuntu. If your BIOS doesn’t let you boot using a USB flash drive, don’t worry, we’ve got you covered! Use a Healthy Hard Drive If your computer has more than one hard drive, or your hard drive is healthy and you’re in Ubuntu for non-recovery reasons, then accessing your hard drive is easy as pie, even if the hard drive is formatted for Windows. To access a hard drive, it must first be mounted. To mount a healthy hard drive, you just have to select it from the Places menu at the top-left of the screen. You will have to identify your hard drive by its size. Clicking on the appropriate hard drive mounts it, and opens it in a file browser. You can now move files to this hard drive by drag-and-drop or copy-and-paste, both of which are done the same way they’re done in Windows. Once a hard drive, or other external storage device, is mounted, it will show up in the /media directory. To see a list of currently mounted storage devices, navigate to /media by clicking on File System in a File Browser window, and then double-clicking on the media folder. Right now, our media folder contains links to the hard drive, which Ubuntu has assigned a terribly uninformative label, and the PLoP Boot Manager CD that is currently in the CD-ROM drive. Connect a USB Hard Drive or Flash Drive An external USB hard drive gives you the advantage of portability, and is still large enough to store an entire hard disk dump, if need be. Flash drives are also very quick and easy to connect, though they are limited in how much they can store. When you plug a USB hard drive or flash drive in, Ubuntu should automatically detect it and mount it. It may even open it in a File Browser automatically. Since it’s been mounted, you will also see it show up on the desktop, and in the /media folder. Once it’s been mounted, you can access it and store files on it like you would any other folder in Ubuntu. If, for whatever reason, it doesn’t mount automatically, click on Places in the top-left of your screen and select your USB device. If it does not show up in the Places list, then you may need to format your USB drive. To properly remove the USB drive when you’re done moving files, right click on the desktop icon or the folder in /media and select Safely Remove Drive. If you’re not given that option, then Eject or Unmount will effectively do the same thing. Connect to a Windows PC on your Local Network If you have another PC or a laptop connected through the same router (wired or wireless) then you can transfer files over the network relatively quickly. To do this, we will share one or more folders from the machine booted up with the Ubuntu Live CD over the network, letting our Windows PC grab the files contained in that folder. As an example, we’re going to share a folder on the desktop called ToShare. Right-click on the folder you want to share, and click Sharing Options. A Folder Sharing window will pop up. Check the box labeled Share this folder. A window will pop up about the sharing service. Click the Install service button. Some files will be downloaded, and then installed. When they’re done installing, you’ll be appropriately notified. You will be prompted to restart your session. Don’t worry, this won’t actually log you out, so go ahead and press the Restart session button. The Folder Sharing window returns, with Share this folder now checked. Edit the Share name if you’d like, and add checkmarks in the two checkboxes below the text fields. Click Create Share. Nautilus will ask your permission to add some permissions to the folder you want to share. Allow it to Add the permissions automatically. The folder is now shared, as evidenced by the new arrows above the folder’s icon. At this point, you are done with the Ubuntu machine. Head to your Windows PC, and open up Windows Explorer. Click on Network in the list on the left, and you should see a machine called UBUNTU in the right pane. Note: This example is shown in Windows 7; the same steps should work for Windows XP and Vista, but we have not tested them. Double-click on UBUNTU, and you will see the folder you shared earlier! As well as any other folders you’ve shared from Ubuntu. Double click on the folder you want to access, and from there, you can move the files from the machine booted with Ubuntu to your Windows PC. Upload to an Online Service There are many services online that will allow you to upload files, either temporarily or permanently. As long as you aren’t transferring an entire hard drive, these services should allow you to transfer your important files from the Ubuntu environment to any other machine with Internet access. We recommend compressing the files that you want to move, both to save a little bit of bandwidth, and to save time clicking on files, as uploading a single file will be much less work than a ton of little files. To compress one or more files or folders, select them, and then right-click on one of the members of the group. Click Compress…. Give the compressed file a suitable name, and then select a compression format. We’re using .zip because we can open it anywhere, and the compression rate is acceptable. Click Create and the compressed file will show up in the location selected in the Compress window. Dropbox If you have a Dropbox account, then you can easily upload files from the Ubuntu environment to Dropbox. There is no explicit limit on the size of file that can be uploaded to Dropbox, though a free account begins with a total limit of 2 GB of files in total. Access your account through Firefox, which can be opened by clicking on the Firefox logo to the right of the System menu at the top of the screen. Once into your account, press the Upload button on top of the main file list. Because Flash is not installed in the Live CD environment, you will have to switch to the basic uploader. Click Browse…find your compressed file, and then click Upload file. Depending on the size of the file, this could take some time. However, once the file has been uploaded, it should show up on any computer connected through Dropbox in a matter of minutes. Google Docs Google Docs allows the upload of any type of file – making it an ideal place to upload files that we want to access from another computer. While your total allocation of space varies (mine is around 7.5 GB), there is a per-file maximum of 1 GB. Log into Google Docs, and click on the Upload button at the top left of the page. Click Select files to upload and select your compressed file. For safety’s sake, uncheck the checkbox concerning converting files to Google Docs format, and then click Start upload. Go Online – Through FTP If you have access to an FTP server – perhaps through your web hosting company, or you’ve set up an FTP server on a different machine – you can easily access the FTP server in Ubuntu and transfer files. Just make sure you don’t go over your quota if you have one. You will need to know the address of the FTP server, as well as the login information. Click on Places > Connect to Server… Choose the FTP (with login) Service type, and fill in your information. Adding a bookmark is optional, but recommended. You will be asked for your password. You can choose to remember it until you logout, or indefinitely. You can now browse your FTP server just like any other folder. Drop files into the FTP server and you can retrieve them from any computer with an Internet connection and an FTP client. Conclusion While at first the Ubuntu Live CD environment may seem claustrophobic, it has a wealth of options for connecting to peripheral devices, local computers, and machines on the Internet – and this article has only scratched the surface.

• HDMI video connection cuts top and bottom borders of screen

  - by Luis Alvarado

  Ok this is an extension of another problem I had with a VGA connection and an Nvidia Geforce GT 440 card. Here is goes the explanation of this particular problem: I have a Soneview 32' TV. This TV has many connections including VGA (First reason I bought it), HDMI (Second reason but did not have a HDMI cable at that time) and DVI. I have had this TV for little over a month now, actually I had it to celebrate the release of Ubuntu 11.10 and started using it exactly on that date (I know too much fan there but hey, I like geek stuff). I started using it with the VGA cable. After 2 weeks I bought an Nvidia GT440 card. The previous 9500GT was working correctly with no problems whatsoever. I installed the GT440 and the first problem that I encountered using this latest card is mentioned here: Nvidia GT 440 black screen problem when loading lightdm greeter. The solution to this problem was to actually disconnect then connect again the VGA cable. This would result in the screen showing me the lightdm screen for my login. If I did not disconnect then connect the cable I could be there forever thinking that there is no video signal. I got tired of looking for answers that did not work and for solutions that made me literally have to install Ubuntu again. I just went and bought a HDMI cable and changed the VGA one for that one. It worked and I did not have to disconnect/connect the cable but now I have this problem when using any resolution. My normal resolution is 1920x1080 (This TV is 1080HD) so in VGA I could use this resolution with no problem, but on HDMI am getting the borders cut out. Here is a pic: As you can see from the PIC, the Launcher icons only show less than 50% of their witdh. Forget about the top and bottom parts, I can access them with the mouse but I can not visualize them in the screen. It is like it's outside of the TVs view. Basically there is like 20 to 30 pixels gone from all sides. I searched around and came to running xrand --verbose to see what it could detect from the TV. I got this: cyrex@cyrex:~$ xrandr --verbose xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080 default connected 1920x1080+0+0 (0x164) normal (normal) 0mm x 0mm Identifier: 0x163 Timestamp: 465485 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: 1920x1080 (0x164) 103.7MHz *current h: width 1920 start 0 end 0 total 1920 skew 0 clock 54.0KHz v: height 1080 start 0 end 0 total 1080 clock 50.0Hz 1920x1080 (0x165) 105.8MHz h: width 1920 start 0 end 0 total 1920 skew 0 clock 55.1KHz v: height 1080 start 0 end 0 total 1080 clock 51.0Hz 1920x1080 (0x166) 107.8MHz h: width 1920 start 0 end 0 total 1920 skew 0 clock 56.2KHz v: height 1080 start 0 end 0 total 1080 clock 52.0Hz 1920x1080 (0x167) 109.9MHz h: width 1920 start 0 end 0 total 1920 skew 0 clock 57.2KHz v: height 1080 start 0 end 0 total 1080 clock 53.0Hz 1920x1080 (0x168) 112.0MHz h: width 1920 start 0 end 0 total 1920 skew 0 clock 58.3KHz v: height 1080 start 0 end 0 total 1080 clock 54.0Hz 1920x1080 (0x169) 114.0MHz h: width 1920 start 0 end 0 total 1920 skew 0 clock 59.4KHz v: height 1080 start 0 end 0 total 1080 clock 55.0Hz 1680x1050 (0x16a) 98.8MHz h: width 1680 start 0 end 0 total 1680 skew 0 clock 58.8KHz v: height 1050 start 0 end 0 total 1050 clock 56.0Hz 1680x1050 (0x16b) 100.5MHz h: width 1680 start 0 end 0 total 1680 skew 0 clock 59.9KHz v: height 1050 start 0 end 0 total 1050 clock 57.0Hz 1600x1024 (0x16c) 95.0MHz h: width 1600 start 0 end 0 total 1600 skew 0 clock 59.4KHz v: height 1024 start 0 end 0 total 1024 clock 58.0Hz 1440x900 (0x16d) 76.5MHz h: width 1440 start 0 end 0 total 1440 skew 0 clock 53.1KHz v: height 900 start 0 end 0 total 900 clock 59.0Hz 1360x768 (0x171) 65.8MHz h: width 1360 start 0 end 0 total 1360 skew 0 clock 48.4KHz v: height 768 start 0 end 0 total 768 clock 63.0Hz 1360x768 (0x172) 66.8MHz h: width 1360 start 0 end 0 total 1360 skew 0 clock 49.2KHz v: height 768 start 0 end 0 total 768 clock 64.0Hz 1280x1024 (0x173) 85.2MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 66.6KHz v: height 1024 start 0 end 0 total 1024 clock 65.0Hz 1280x960 (0x176) 83.6MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 65.3KHz v: height 960 start 0 end 0 total 960 clock 68.0Hz 1280x960 (0x177) 84.8MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 66.2KHz v: height 960 start 0 end 0 total 960 clock 69.0Hz 1280x720 (0x178) 64.5MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 50.4KHz v: height 720 start 0 end 0 total 720 clock 70.0Hz 1280x720 (0x179) 65.4MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 51.1KHz v: height 720 start 0 end 0 total 720 clock 71.0Hz 1280x720 (0x17a) 66.4MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 51.8KHz v: height 720 start 0 end 0 total 720 clock 72.0Hz 1152x864 (0x17b) 72.7MHz h: width 1152 start 0 end 0 total 1152 skew 0 clock 63.1KHz v: height 864 start 0 end 0 total 864 clock 73.0Hz 1152x864 (0x17c) 73.7MHz h: width 1152 start 0 end 0 total 1152 skew 0 clock 63.9KHz v: height 864 start 0 end 0 total 864 clock 74.0Hz ....Many Resolutions later... 320x200 (0x1d1) 10.2MHz h: width 320 start 0 end 0 total 320 skew 0 clock 31.8KHz v: height 200 start 0 end 0 total 200 clock 159.0Hz 320x175 (0x1d2) 9.0MHz h: width 320 start 0 end 0 total 320 skew 0 clock 28.0KHz v: height 175 start 0 end 0 total 175 clock 160.0Hz 1920x1080 (0x1dd) 333.8MHz h: width 1920 start 0 end 0 total 1920 skew 0 clock 173.9KHz v: height 1080 start 0 end 0 total 1080 clock 161.0Hz If it helps, the Refresh Rate at 1920x1080 is 60. There is a flickering effect at this resolution using HDMI but not VGA which I imagine is related to the borders cut off issue am asking here. I have also done the following but this will only solve the problem on lower resolutions than 1920x1080 or on others TV (My father has a Sony TV where this problem is also solved): NVIDIA WAY Go to Nvidia-Settings and there will be an option that will have more features if a HDMI cable is connected. In the next pic the option is DFP-1 (CNDLCD) but this name changes depending on what device the PC is connected to: Uncheck Force Full GPU Scaling What this will do for resolutions LOWER than 1920x1080 (At least in my case) is solve the flickering problem and fix the borders cut by the monitor. Save to Xorg.conf file the changes made after changing to a resolution acceptable to your eyes. TV WAY If you TV has OSD Menu and this menu has options for scanning the screen resolution or auto adjusting to it, disable them. Specifically the option about SCAN. If you have an option for AV Mode disable it. Basically disable any option that needs to scan and scale the resolution. Test one by one. In the case of my father's TV this did it. In my case, the Nvidia solved it for lower resolutions. NOTE: In the case this is not solved in the next couple of weeks I will add this as the answer but take into consideration that the issue is still active with 1920x1080 resolutions.

• How to Increase the VMWare Boot Screen Delay

  - by Trevor Bekolay

  If you’ve wanted to try out a bootable CD or USB flash drive in a virtual machine environment, you’ve probably noticed that VMWare’s offerings make it difficult to change the boot device. We’ll show you how to change these options. You can do this either for one boot, or permanently for a particular virtual machine. Even experienced users of VMWare Player or Workstation may not recognize the screen above – it’s the virtual machine’s BIOS, which in most cases flashes by in the blink of an eye. If you want to boot up the virtual machine with a CD or USB key instead of the hard drive, then you’ll need more than an eye’s-blink to press Escape and bring up the Boot Menu. Fortunately, there is a way to introduce a boot delay that isn’t exposed in VMWare’s graphical interface – you have to edit the virtual machine’s settings file (a .vmx file) manually. Editing the Virtual Machine’s .vmx Find the .vmx file that contains the settings for your virtual machine. You chose a location for this when you created the virtual machine – in Windows, the default location is a folder called My Virtual Machines in your My Documents folder. In VMWare Workstation, the location of the .vmx file is listed on the virtual machine’s tab. If in doubt, search your hard drive for .vmx files. If you don’t want to use Windows default search, an awesome utility that locates files instantly is Everything. Open the .vmx file with any text editor. Somewhere in this file, enter in the following line… save the file, then close out of the text editor: bios.bootdelay = 20000 This will introduce a 20 second delay when the virtual machine loads up, giving you plenty of time to press the Escape button and access the boot menu. The number in this line is just a value in milliseconds, so for a five second boot delay, enter 5000, and so on. Change Boot Options Temporarily Now, when you boot up your virtual machine, you’ll have plenty of time to enter one of the keystrokes listed at the bottom of the BIOS screen on boot-up. Press Escape to bring up the Boot Menu. This allows you to select a different device to boot from – like a CD drive. Your selection will be forgotten the next time you boot up this virtual machine. Change Boot Options Permanently When the BIOS screen comes up, press F2 to enter the BIOS Setup menu. Switch to the Boot tab, and change the ordering of the items by pressing the “+” key to move items up on the list, and the “-” key to move items down the list. We’ve switched the order so that the CD-ROM Drive boots first. Once you make this change permanent, you may want to re-edit the .vmx file to remove the boot delay. Boot from a USB Flash Drive One thing that is noticeably missing from the list of boot options is a USB device. VMWare’s BIOS just does not allow this, but we can get around that limitation using the PLoP Boot Manager that we’ve previously written about. And as a bonus, since everything is virtual anyway, there’s no need to actually burn PLoP to a CD. Open the settings for the virtual machine you want to boot with a USB drive. Click on Add… at the bottom of the settings screen, and select CD/DVD Drive. Click Next. Click the Use ISO Image radio button, and click Next. Browse to find plpbt.iso or plpbtnoemul.iso from the PLoP zip file. Ensure that Connect at power on is checked, and then click Finish. Click OK on the main Virtual Machine Settings page. Now, if you use the steps above to boot using that CD/DVD drive, PLoP will load, allowing you to boot from a USB drive! Conclusion We’re big fans of VMWare Player and Workstation, as they let us try out a ton of geeky things without worrying about harming our systems. By introducing a boot delay, we can add bootable CDs and USB drives to the list of geeky things we can try out.

• Sound issues after trying everything

  - by Lerp

  I cannot get my sound working properly, no matter what I do, there's always some problem. It's very annoying as it's the only thing preventing me from making Ubuntu my main OS. At the moment my sound always plays through both my speakers and my headphones regardless except the sound through the headphones is crackly. It is also a bit quiet even though everything is maxed. I've managed to improve the situation to a point where the sound out of my speakers is perfect but I have none at all from my headphones. I do have two connectors listed in the sound settings but regardless of which one is selected it always plays through the speakers. I think this might have something to do with the fact that my speakers are plugging into the front of my computer, typically the headphone jack, and my headphones are plugging into the back but when I try disconnecting the speakers from the front there is still no sound from the headphones. I fixed the speaker sound by going through the sound settings and making sure they were all set to 100% then rebooting. Things I have tried: Maxing everything and unmuting everything in alsamixer Uninstalling pulseaudio Making gstreamer use only alsa via gstreamer-properties. This worked with the sound test button including independent sound between headphones and speakers but when I reset the computer it no longer worked. So I tried setting it manually in gconf-editor which didn't work either. Reinstalling alsa and pulseaudio Setting the model in /etc/modprobe.d/alsa-base.conf to 6stack and 6stack-dig neither worked. Upgrading to 12.10 Here's some command output to help you diagnose my problem. aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 2: AD198x Headphone [AD198x Headphone] Subdevices: 1/1 Subdevice #0: subdevice #0 sudo lshw -C sound *-multimedia description: Audio device product: 82801JI (ICH10 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:70 memory:f7ff8000-f7ffbfff cat /proc/asound/card*/codec* | grep "Codec" Codec: Analog Devices AD1989B cat /etc/modprobe.d/alsa-base.conf # autoloader aliases install sound-slot-0 /sbin/modprobe snd-card-0 install sound-slot-1 /sbin/modprobe snd-card-1 install sound-slot-2 /sbin/modprobe snd-card-2 install sound-slot-3 /sbin/modprobe snd-card-3 install sound-slot-4 /sbin/modprobe snd-card-4 install sound-slot-5 /sbin/modprobe snd-card-5 install sound-slot-6 /sbin/modprobe snd-card-6 install sound-slot-7 /sbin/modprobe snd-card-7 # Cause optional modules to be loaded above generic modules install snd /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-ioctl32 ; /sbin/modprobe --quiet --use-blacklist snd-seq ; } # # Workaround at bug #499695 (reverted in Ubuntu see LP #319505) install snd-pcm /sbin/modprobe --ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-pcm-oss ; : ; } install snd-mixer /sbin/modprobe --ignore-install snd-mixer $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-mixer-oss ; : ; } install snd-seq /sbin/modprobe --ignore-install snd-seq $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; /sbin/modprobe --quiet --use-blacklist snd-seq-oss ; : ; } # install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; : ; } # Cause optional modules to be loaded above sound card driver modules install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-emu10k1-synth ; } install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq ; } # Load saa7134-alsa instead of saa7134 (which gets dragged in by it anyway) install saa7134 /sbin/modprobe --ignore-install saa7134 $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist saa7134-alsa ; : ; } # Prevent abnormal drivers from grabbing index 0 options bt87x index=-2 options cx88_alsa index=-2 options saa7134-alsa index=-2 options snd-atiixp-modem index=-2 options snd-intel8x0m index=-2 options snd-via82xx-modem index=-2 options snd-usb-audio index=-2 options snd-usb-caiaq index=-2 options snd-usb-ua101 index=-2 options snd-usb-us122l index=-2 options snd-usb-usx2y index=-2 # Ubuntu #62691, enable MPU for snd-cmipci options snd-cmipci mpu_port=0x330 fm_port=0x388 # Keep snd-pcsp from being loaded as first soundcard options snd-pcsp index=-2 # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 options snd-hda-intel model=6stack

• Multiple Audio Issues

  - by Lerp

  I am having issues with my audio on Ubuntu 12.04, I will try and give as much detail as possible so sorry if there's too much detail. The Problem Audio plays from both speakers and headphone regardless of what connector I choose and regardless of the profile I use. The microphone is constantly being played through headphones & speakers. The headphone audio is extremely quiet but plays from both ears when I select "Headphones" for the connector in Sound Settings. The headphone audio only plays from one ear and is quiet (but not as quiet as above) when I select "Analogue Output" for the connector in Sound Settings. I can only select "Headphones" as the connector in Sound Settings if I set the profile to either "Analogue Stereo Output/Duplex", all others only allow me to choose "Analogue Output" for the connector. Despite the headphone sound issues, the speaker sound is fine apart from the fact that I am not able to select which output is used, they just both play. My headphone and microphone are plugged into the front and my speakers are plugged into the back. What I have tried I have put everything in alsamixer to 100 apart from "Front Mic Boost" which I have set to 0.

  My last installation of Ubuntu 12.04 on a machine using an ASUS Q87M-E motherboard with an Intel I217LM Ethernet controller has failed to detect the ethernet card. The only thing displayed by ifconfig -a is the loopback. I double-checked in the BIOS, and the controller should be online. $ rfkill list all 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no $ lspci 00:00.0 Host bridge: Intel Corporation Haswell DRAM Controller (rev 06) 00:01.0 PCI bridge: Intel Corporation Haswell PCI Express x16 Controller (rev 06) 00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06) 00:03.0 Audio device: Intel Corporation Haswell HD Audio Controller (rev 06) 00:14.0 USB controller: Intel Corporation Lynx Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Lynx Point MEI Controller #1 (rev 04) 00:16.3 Serial controller: Intel Corporation Lynx Point KT Controller (rev 04) 00:19.0 Ethernet controller: Intel Corporation Device 153a (rev 04) 00:1a.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Lynx Point HD Audio Controller (rev 04) 00:1d.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Lynx Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Lynx Point 6-Port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation Lynx Point SMBus Controller (rev 04) $ lsmod Module Size Used by vesafb 13844 1 snd_hda_codec_realtek 224173 1 arc4 12529 2 joydev 17693 0 usbhid 47238 0 hid 99636 1 usbhid rfcomm 47604 0 rt73usb 31735 0 crc_itu_t 12707 1 rt73usb rt2x00usb 20808 1 rt73usb rt2x00lib 55326 2 rt73usb,rt2x00usb mac80211 506862 2 rt2x00usb,rt2x00lib cfg80211 205774 2 rt2x00lib,mac80211 eeepc_wmi 13109 0 bnep 18281 2 asus_wmi 24456 1 eeepc_wmi sparse_keymap 13890 1 asus_wmi psmouse 97485 0 bluetooth 180153 10 rfcomm,bnep ppdev 17113 0 snd_hda_intel 33719 6 snd_hda_codec 127706 2 snd_hda_codec_realtek,snd_hda_intel snd_seq_midi 13324 0 snd_hwdep 17764 1 snd_hda_codec snd_rawmidi 30748 1 snd_seq_midi serio_raw 13211 0 snd_pcm 97275 2 snd_hda_intel,snd_hda_codec snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61929 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq parport_pc 32866 1 snd 79041 21 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_rawmidi,snd_pcm,snd_seq,snd_timer,snd_seq_device video 19651 0 soundcore 15091 1 snd wmi 19256 1 asus_wmi snd_page_alloc 18529 2 snd_hda_intel,snd_pcm mac_hid 13253 0 lp 17799 0 parport 46562 3 ppdev,parport_pc,lp $ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1091 errors:0 dropped:0 overruns:0 frame:0 TX packets:1091 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:80048 (80.0 KB) TX bytes:80048 (80.0 KB) wlan0 Link encap:Ethernet HWaddr 00:fd:07:91:a8:b9 inet addr:172.16.42.4 Bcast:172.16.42.255 Mask:255.255.255.0 inet6 addr: fe80::2fd:7ff:fe91:a8b9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:56644 errors:0 dropped:0 overruns:0 frame:0 TX packets:36417 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:85270918 (85.2 MB) TX bytes:3413849 (3.4 MB) additionally, running sudo lshw -C network returns: *-network UNCLAIMED description: Ethernet Controller [...] I'm pretty stumped at this point. This doesn't sound like a very uncommon ethernet controller and I figured it would be picked up by the system. Does anybody have advice for how to deal with this?

Is this a real fix or is there a better way?

• Repurpose a Wire Basket as a Game Controller Organizer

  - by Jason Fitzpatrick

  If you’re looking for an easy way to organize your console controllers, this simple repurposing hack turns an IKEA wire basket intended for managing cable clutter into a game controller stand. You won’t need a Dremel tool to install this hack; all you need to do to follow in the foot steps of IKEAHackers reader Leslie is to install a SIGNUM cable basket (or similar cable organizer) upside down so loom curves up instead of down. Instant wire cradle for your controllers (or possibly an open air charging station for your small electronics). Check out the link below for more details.

• Expensive HDMI Cables Make No Difference

  - by Jason Fitzpatrick

  While we’re no strangers to spreading the news that expensive HDMI cables are a ripoff, we’re happy to share yet another study that shows there’s zero difference between a $5 cable and a $95 one. Over at the British hardware review site Expert Reviews, they subjected a wide selection of HDMI cables to extensive tests in a bid to produce the end-all examination of whether or not a premium HDMI cable could actually produce a better signal. They used capture cards, pixel-by-pixel comparison of output, and other techniques to pick over individual frames until they ultimately reached the same conclusion everyone outside of the Monster sales staff had already reached: you’re getting absolutely no benefit to spending $100 on cable that can be had for under five bucks.

• How to avoid HDD spin up at system start? (Ubuntu from SSD)

  - by Oliver

  Thanks to hdparm -B1 /dev/sdb my HDD does no longer spin up when powered up on boot. But after completing the BIOS POST messages and starting Ubuntu the HDD gets a signal over the SATA data cable and spins up. Leaving the data cable (but still with plugged in SATA power cable) let the system boot up completely from my SSD without spinning up the HDD. What causes the HDD to spin up? Maybe Grub2? Edit: nope, doesn't seem to be Grub2 that spins up the drive. I just set up Grub to show its menu without timer. Nothings happens until I hit the Ubuntu standard boot option, then a few seconds later the drive spins up.

• The Power to Control Power

  - by speakjava

  I'm currently working on a number of projects using embedded Java on the Raspberry Pi and Beagle Board.  These are nice and small, so don't take up much room on my desk as you can see in this picture. As you can also see I have power and network connections emerging from under my desk.  One of the (admittedly very minor) drawbacks of these systems is that they have no on/off switch.  Instead you insert or remove the power connector (USB for the RasPi, a barrel connector for the Beagle).  For the Beagle Board this can potentially be an issue; with the micro-SD card located right next to the connector it has been known for people to eject the card when trying to power off the board, which can be quite serious for the hardware. The alternative is obviously to leave the boards plugged in and then disconnect the power from the outlet.  Simple enough, but a picture of underneath my desk shows that this is not the ideal situation either. This made me think that it would be great if I could have some way of controlling a mains voltage outlet using a remote switch or, even better, from software via a USB connector.  A search revealed not much that fit my requirements, and anything that was close seemed very expensive.  Obviously the only way to solve this was to build my own.Here's my solution.  I decided my system would support both control mechanisms (remote physical switch and USB computer control) and be modular in its design for optimum flexibility.  I did a bit of searching and found a company in Hong Kong that were offering solid state relays for 99p plus shipping (£2.99, but still made the total price very reasonable).  These would handle up to 380V AC on the output side so more than capable of coping with the UK 240V supply.  The other great thing was that being solid state, the input would work with a range of 3-32V and required a very low current of 7.5mA at 12V.  For the USB control an Arduino board seemed the obvious low-cost and simple choice.  Given the current requirments of the relay, the Arduino would not require the additional power supply and could be powered just from the USB.Having secured the relays I popped down to Homebase for a couple of 13A sockets, RS for a box and an Arduino and Maplin for a toggle switch.  The circuit is pretty straightforward, as shown in the diagram (only one output is shown to make it as simple as possible).  Originally I used a 2 pole toggle switch to select the remote switch or USB control by switching the negative connections of the low voltage side.  Unfortunately, the resistance between the digital pins of the Arduino board was not high enough, so when using one of the remote switches it would turn on both of the outlets.  I changed to a 4 pole switch and isolated both positive and negative connections. IMPORTANT NOTE: If you want to follow my design, please be aware that it requires working with mains voltages.  If you are at all concerned with your ability to do this please consult a qualified electrician to help you.It was a tight fit, especially getting the Arduino in, but in the end it all worked.  The completed box is shown in the photos. The remote switch was pretty simple just requiring the squeezing of two rocker switches and a 9V battery into the small RS supplied box.  I repurposed a standard stereo cable with phono plugs to connect the switch box to the mains outlets.  I chopped off one set of plugs and wired it to the rocker switches.  The photo shows the RasPi and the Beagle board now controllable from the switch box on the desk. I've tested the Arduino side of things and this works fine.  Next I need to write some software to provide an interface for control of the outlets.  I'm thinking a JavaFX GUI would be in keeping with the total overkill style of this project.

• How Fiber Optic Cables Are Made and Laid Across the Sea [Science]

  - by Jason Fitzpatrick

  We don’t know about you but yesterday’s video about how fiber optic cables work just made us more curious. Check out how the cables are made and laid across the sea. In the above video we see how fiber optic strands are manufactured, including how the draw tower mentioned in yesterday’s video works. Once the strands are manufactured, where do they go and how are they used? In the video below we see Alcatel-Lucent’s Ile de Sein, one of the largest and most powerful cable laying ships in the world. Check out the video to see cable storage wells that look like small stadiums. Finding out how the cables are made and what kind of planning and machinery it takes to lay them across the ocean is just as interesting as how they work.
