• Periodic clicking sound from PC speaker

  - by John J. Camilleri

  After an update some months ago, my laptop has begun making a low, repeated clicking sound every few seconds. It is not being generated through the regular sound system, as altering the volume and even muting the sound does not make any difference. My regular audio works fine, by the way, so I am guessing this is some sort of PC speaker, since I cannot hear the click when I listen through regular headphones. Strangely, when I open the sound settings dialog the click magically disappears. I don't need to change any settings; if I simply leave the dialog open in the background then the problem disappears. Any ideas what this could be? I am running regular Ubuntu 12.04, and this is the output from lspci -v | grep -A7 -i "audio": 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 0349 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 54200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel

• How to change the volume of left channel using pulseaudio

  - by user2622247

  I am recording the video using logitech camera and bluetooth microphone. Logitech can used for recording both audio and video. When I turn on bluetooth microphone in the middle of recording, it is replacing the logitech audio channel due to this we are getting the bluetooth audio from the left channel. But when I turn off the bluetooth then I get the logitech audio on left channel but the volume is very low and also getting the some noise. I am using PulseAudio and ffmpeg for recording purpose. So how can I increase / change the volume of left channel during runtime?

• Domain Transfer Protection - need advice

  - by Jack

  Hey, I am about to purchase a domain name for a bit of money. I do not personally know the person who I am purchasing the domain name from, we have only chatted via email. The proposed process for the transfer is: The owner of the domain lowest the domain name security and emails me the domain password, I request the transfer After the request, I transfer the money via PayPal When the money has been cleared the current domain name owner confirms the transfer via the link that he receives in that email I wait for it to be transferred. The domain is currently registered with DirectNIC - http://www.directnic.com/ Is this the best practice? Seeing I am paying a bit of money for this domain name, I am worried that after the money has been cleared that I won't see the domain name or hear from the current domain name owner again. Is there a 'domain governing body' which I can report to if this is the case? Is the proposed transfer process the best solution? Any advice would be awesome. Thanks! Jack

• Loud and annoying noise on login

  - by searchfgold6789

  I have a PC with Kubuntu 13.10 64-bit on it. The problem is that whenever I log in (automatic log in is enabled), there is a loud double-click noise that sounds from the speakers whether the volume is muted or not. I have two sound cards; the motherboard audio, which is disabled in the BIOS, and the Creative! Labs Sound Blaster X-Fi SB0460, which I have normal speakers plugged into. Does anyone know how to fix this? Relative lspci lines: 00:01.1 Audio device: Advanced Micro Devices, Inc.

• copy rows before updating them to preserve archive in Postgres

  - by punkish

  I am experimenting with creating a table that keeps a version of every row. The idea is to be able to query for how the rows were at any point in time even if the query has JOINs. Consider a system where the primary resource is books, that is, books are queried for, and author info comes along for the ride CREATE TABLE authors ( author_id INTEGER NOT NULL, version INTEGER NOT NULL CHECK (version > 0), author_name TEXT, is_active BOOLEAN DEFAULT '1', modified_on TIMESTAMP DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (author_id, version) ) INSERT INTO authors (author_id, version, author_name) VALUES (1, 1, 'John'), (2, 1, 'Jack'), (3, 1, 'Ernest'); I would like to be able to update the above like so UPDATE authors SET author_name = 'Jack K' WHERE author_id = 1; and end up with 2, 1, Jack, t, 2012-03-29 21:35:00 2, 2, Jack K, t, 2012-03-29 21:37:40 which I can then query with SELECT author_name, modified_on FROM authors WHERE author_id = 2 AND modified_on < '2012-03-29 21:37:00' ORDER BY version DESC LIMIT 1; to get 2, 1, Jack, t, 2012-03-29 21:35:00 Something like the following doesn't really work CREATE OR REPLACE FUNCTION archive_authors() RETURNS TRIGGER AS $archive_author$ BEGIN IF (TG_OP = 'UPDATE') THEN -- The following fails because author_id,version PK already exists INSERT INTO authors (author_id, version, author_name) VALUES (OLD.author_id, OLD.version, OLD.author_name); UPDATE authors SET version = OLD.version + 1 WHERE author_id = OLD.author_id AND version = OLD.version; RETURN NEW; END IF; RETURN NULL; -- result is ignored since this is an AFTER trigger END; $archive_author$ LANGUAGE plpgsql; CREATE TRIGGER archive_author AFTER UPDATE OR DELETE ON authors FOR EACH ROW EXECUTE PROCEDURE archive_authors(); How can I achieve the above? Or, is there a better way to accomplish this? Ideally, I would prefer to not create a shadow table to store the archived rows.

• Why did this command make my Ubuntu more awesome than before?

  - by the_misfit

  After running Ubuntu for months and liking it, I for the first time wanted to use headphones and was trying to get them to work so I ran the code in step 1 https://help.ubuntu.com/community/SoundTroubleshootingProcedure -- the result was an improvement in performance, resolution, and audio.. a vast improvement. What does that suggest about what was wrong with my settings before if running this improved system performance, graphics, and my audio problem? The command is: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami`

  I have two Radeon 6450 graphics cards in my computer, with three screens. Only the screens plugged into the first graphics card are recognized and configurable in the displays setting panel.

• Intermittent sound on an Medion Akoya S5610

  - by ej159

  The sound on my machine (Medion Akoya S5610) works intermittently. If I reboot enough times I do get sound. This happened before I upgraded, when running Oneiric too. I have fiddled around with alsa-base.conf, putting in different values for model in options snd-hda-intel model=but still the issue persists (although I get the impression that I am more like to have sound on the next reboot if I have edited that file although I can't be sure of this). Adding index=0 does not help the situation either. I have been thinking that this problem could be related some how to the order that driver modules are loaded. The snd-hda-intel module is also used for the sound card (ALC888) in my graphics card. Could it be that these are some how competing? If so, how do I add a preference when they are using the same module? This is the result of lspci -nn | grep Audio (when sound was not working): 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) 01:00.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI RV620 HDMI Audio [Radeon HD 3400 Series] [1002:aa28] I've been wrestling with this problem for ages and ages and have spent days looking for answers on forums but to no avail so I would appreciate any help you can give.

• How do you Bind to a ComboBox in a DataTemplate?

  - by discwiz

  I have a listbox that is bound to an observable collection of Audio (custom class). The Audio class has two properties, DisplayText (string) and a property called TarpIds (Observable Collection of Integer). I need to allow the user to change the TarpID in the combo box for each list item displayed and catch the selection change. I created a DataTemplate that styles the DisplayText property from the Audio object and adds a ComboBox to display the available TarpIDs for this audio (These are dynamic and unique to each Audio). The DisplayText works great, but I can not get the TarpIDs to display in the ComboBox. Here is what I have so far and thanks for any help. FYI I set the ItemSource at run time that binds the ListUploadAudio to the Observable Collection of Audio. <Border BorderBrush="Red" Background="WhiteSmoke" CornerRadius="8"> <Border.Resources> <DataTemplate x:Key="UploadLayout" DataType="Audio"> <StackPanel Orientation="Vertical"> <TextBlock Text="{Binding Path=DisplayText}" FontWeight="Bold" Foreground="Blue"> </TextBlock> <ComboBox x:Name="ListBoxTarpIDs" ItemsSource="{Binding Path=TarpIds}"> </ComboBox> </StackPanel> </DataTemplate> </Border.Resources> <ListBox x:Name="ListUploadAudio" BorderBrush="Transparent" Background="Transparent" Width="230" Margin="10" Height="200" IsSynchronizedWithCurrentItem="True" SelectionMode="Multiple" ItemTemplate="{DynamicResource UploadLayout}"> </ListBox> </Border>

• Logitech webcam device only recognised by one software, without drivers

  - by Ben Franchuk

  A couple weeks ago I purchased a Logitech webcam at a garage sale; It did not come with any driver DVDs or anything like that. I plugged it in, turned on my computer, and continued work as usual. I did not at the time (and still have not) gotten any drivers for the device. Recently, though, I started up an audio software named as Cubase, only to find that it was picking up audio reads off of... something. I checked my sound card, and everything else plugged into my computer, but couldn't find where in the world this audio was being picked up from. There were no microphones listed in the device managers, and no "unknown devices" or whatever. Everything seemed as it always was. Running out of ideas, i blew an air-horn directly into the general area of the webcam, located directly in front of me. Sure enough, the audio peaked, indicating that the microphone was definitely in the webcam and that Cubase was somehow picking up this audio, even without drivers. The software lists the device as a "Universal USB Microphone". Adobe Audition, Soundbooth, and other audio applications cannot find the device either. Why is it that this one software (Cubase) can use this device without a driver, while every other piece of software on the computer can't? Not even the operating system can recognize it.

• Picking a linux compatible motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• My Linux desktop sees my HDMI-connected monitor, but my monitor says "No signal"

  - by hrunting

  I have a Gigabyte H55M-UD2H motherboard and an Acer S271HL monitor. When I connect the monitor to the motherboard via VGA, signal works perfectly. When I connect the monitor via HDMI, the system "sees" the connection, but the monitor receives no signal (the monitor shows a blue box which reads "No Signal" and then the monitor goes into power-saving state). Some fun facts about this: if I hook a different monitor to this box via HDMI, the monitor receives the output without issue (same computer/motherboard, same cable, different monitor) if I connect a different computer to the monitor via HDMI, the monitor receives the output without issue (different computer, same cable, same monitor) no signal is received whether in the OS or in the BIOS there are no BIOS options for controlling video output other than for selection of onboard vs. PCI/PCI-E-based video card (the system has no dedicated video card installed) The box is running Linux, so I have the output of xrandr which shows the connection and the monitor modes detected via DDC: ~$ xrandr --prop Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 598mm x 336mm EDID: 00ffffffffffff000472ca028d128022 1c160103803c2278ca7b45a4554aa227 0b5054bfef80714f8140818081c08100 9500b300d1c0023a801871382d40582c 450056502100001e000000fd00384c1f 5311000a202020202020000000fc0053 323731484c0a202020202020000000ff 004c55573044303130383531300a01e5 020324f14f0102030405060790111213 1415161f230907078301000067030c00 1000382d023a801871382d40582c4500 56502100001f011d8018711c1620582c 250056502100009f011d007251d01e20 6e28550056502100001e8c0ad08a20e0 2d10103e960056502100001800000000 000000000000000000000000000000de Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on 1920x1080 60.0*+ 50.0 25.0 30.0 1680x1050 59.9 1680x945 60.0 1400x1050 74.9 59.9 1600x900 60.0 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1366x768 60.0 1360x768 60.0 1280x800 74.9 59.9 1152x864 75.0 1280x768 74.9 60.0 1280x720 50.0 60.0 1440x576 25.0 1024x768 75.1 70.1 60.0 1440x480 30.0 1024x576 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 848x480 60.0 720x480 59.9 640x480 72.8 75.0 66.7 60.0 59.9 720x400 70.1 HDMI3 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP2 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP3 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on How do I get this monitor to recognize the output from this HDMI socket?

• picking a linux compatable motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• Hard crash when using bluetooth headset on MacBook Pro and Lion 10.7.2

  - by jtalarico

  I recently picked up a bluetooth headset (Motorola S10-HD) and started using it with my MacBook Pro (17" purchased new in 2010) running Lion 10.7.2. Here's what works - stereo audio: iTunes Spotify Pandora (via browser) games (e.g. Minecraft, which is a Java app) audio from YouTube Plex, VLC, other video players Here's what doesn't work well - stereo audio fails and the headset seems to go into mono (i.e. tinny-as-hell) mode: Google Hangout Skype GoTo Meeting Here's what's just downright catastrophic. If I'm listening to stereo audio and then decide to jump into a Skype call (Google Hangout, or GoTo Meeting), bluetooth often crashes and I can only get things working again by shutting down the device, disabling bluetooth, and getting things back up and running again. But the audio is still horrible, and MUCH better using just a simple set of iPhone earbuds and mic. About 80% of the time during such a call, bluetooth crashes. And about 90% of the time, after the call ends, Skype is shut down, or I try to switch back to playing stereo audio, I get a hard crash!! The gray screen of death descends and I'm told I need to restart my machine. In one such instance, even after a reboot, I could not enable bluetooth again ("Turn Bluetooth On" was grayed out in taskbar). Is this just a weak implementation of bluetooth by Apple, or is this a hardware issue? I've seen others posting similar issues even on the Apple support site indicating that bluetooth headsets are failing left and right, but I haven't seen anyone mention hard crashes.

• Upgrade from Etch to Lenny, server no longer reboots

  - by Jack

  Hi, I just upgraded my (remote) webserver to Lenny from Etch. and no real issue occurs except that I cannot reboot that server. (I can only start in a rescue mode) I recall that a MBR change performed and I am wondering if that could be the reason for this failure. Would someone know how I can revert this MBR change ? I had switched back to my previous linux kernel, still cannot reboot. I would appreciate your help. thanks Jack

• Service monitoring service, which I can ping instead of getting pinged

  - by Jack Juiceson

  I'm looking for a service, which can send me an alert if my program didn't ping(some http request) in X minutes. Pretty much like any service monitoring, but instead of service pinging my server I want, my program to ping the monitor service. This is because our program, can't get incoming connections, yet we need to monitor it's alive. And easiest for us will be to have a service we can ping. Thank you, - Jack

• Setting font size of Closed Captions on iPhone using ffmpeg or mencoder

  - by forthrin

  Does anyone know how to either: Make ffmpeg set subtitle font size in the output video file Make mencoder produce an iPhone-compatible video file (with subtitles) I finally found out how to get Closed Captions video on iPhone, with mkv and srt files as source material. The secret was using the mov_text subtitle codec in ffmpeg (and turning on Closed Captions in the iPhone settings of course): ffmpeg -y -i in.mkv -i in.srt -map 0:0 -map 0:1 -map 1:0 -vcodec copy -acodec aac -ab 256k -scodec mov_text -strict -2 -metadata title="Title" -metadata:s:s:0 language=eng out.mp4 However, the font size appears very small on the iPhone, and I can't find out how to set it with ffmpeg (the iPhone has no option for this). I found out that mencoder has a -subfont-text-scale option, but I don't have a lot of experience with this program. The following, my best attempt so far, produces an output file which is not playable on the iPhone. sudo port install mplayer +mencoder_extras +osd mencoder in.mkv -sub in.srt -o out.mp4 -ovc copy -oac faac -faacopts br=256:mpeg=4:object=2 -channels 2 -srate 48000 -subfont-text-scale 10 -of lavf -lavfopts format=mp4 PS!
