  • Flash in browsers does not play sound accurately using Pulse network audio

    - by Dave M G
    I use PulseAudio to send sound over the LAN to an audio server. When playing any Flash media in Firefox or Chrome, the sound flutters, as if the volume were going up and down every second. The problem does not exhibit with any other software, and I think it's specific to how Flash interacts with my sound set up. How do I get Flash to play nice with the PulseAudio network sound server? Update I have discovered that I can stop the sound fluttering if I follow these steps: Start a Flash video Run pulseaudio --kill on the server Wait about 7 seconds After this, the PulseAudio server automatically respawns, and the sound in the Flash video is perfect. The problem now, though, is that I have to do this every time I start a Flash video. This is obviously not desireable. So, the question is, how do I make whatever it is that makes the sound work when I go through these steps stick so that I don't have to do them? Also, I've uploaded some PulseAudio log output to Pastebin, taken while attempting to play a Flash video, if that helps. I've tried to get logging details from Flash, but despite installing and enabling Flash for debugging, it has not generated any ouput at all. Details I have uploaded an example video of the problem onto Youtube. In the video you can see the opening of a Ted Talk video, and the sound flutters as it plays. The video also stutters while playing back. Here are my sound device output settings:

  • Unity stuck in 2D mode, Nvidia Quadro graphics "unknown", Nvidia-Current active but not in use

    - by Jordan Lund
    I've seen this problem reported under several questions, but I haven't been able to resolve any of it so I thought I'd bring it all in under one umbrella. I started a new job and was given a Dell Precision M6400 laptop with Nvidia Quadro FX 2700M graphics card. It had a previous version of Ubuntu on it, but nobody had any passwords for it so I wiped the drive and did a fresh install of 11.10 from scratch. I didn't do any updates during installation, preferring to do them after boot. Updates ran fine and the system works... except Unity is in 2D mode. System Settings - Additional Drivers shows that Nvidia-Current is active but not in use. System Settings - System Info shows Graphics Driver Unknown, Experience Standard Nvidia X Server Settings is installed and working, re-writing the xorg.conf did nothing. /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro FX 2700M/PCI/SSE2 OpenGL version string: 3.3.0 NVIDIA 285.05.09 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes One suggestion was to do a sudo apt-get --purge remove nvidia* and that resulted in a scrambled screen on boot and a non-bootable installation. Pressing the Delete key on boot allowed me to access the recovery console and do a sudo apt-get install nvidia-current, which brought me back to a working, bootable system. Another suggestion was to edit /etc/default/grub and change the line reading "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to read "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=192MB" thus allocating more video RAM. I did that, followed by a sudo update-grub and a re-boot. No change. Created a brand new standard user and logged on with that account, no change.

  • Simple scan not working after upgrading to 12.10 (Xubuntu)

    - by mydoghasworms
    Since upgrading to 12.10 (Xubuntu), Simple Scan is not working anymore. I got scanning working with Xsane, but only if Simple Scan has not run before.

  • SQL SERVER – 2011 – SEQUENCE is not IDENTITY

    - by pinaldave
    Yesterday I posted blog post on the subject SQL SERVER – 2011 – Introduction to SEQUENCE – Simple Example of SEQUENCE and I received comment where user was not clear about difference between SEQUENCE and IDENTITY. The reality is that SEQUENCE not like IDENTITY. There is very clear difference between them. Identity is about single column. Sequence is always incrementing and it is not dependent on any table. Here is the quick example of the same. USE AdventureWorks2008R2 GO CREATE SEQUENCE [Seq] AS [int] START WITH 1 INCREMENT BY 1 MAXVALUE 20000 GO -- Run five times SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; GO -- Clean Up DROP SEQUENCE [Seq] GO Here is the resultset.

  • DATE function does not support all the dates in DAX by design #powerpivot #tabular #dax

    - by Marco Russo (SQLBI)
    The DATE function in DAX has this simple syntax: DATE( <year>, <month>, <day> ) If you are like me, you never read the BOL notes that says in a clear way that it supports dates beginning with March 1, 1900. In fact, I was wrongly assuming that it would have supported any date that can be represented in a Date data type in Data Models, so all the dates beginning with January 1, 1900. The funny thing is that in some of the BOL documentation you will find that Date data type supports dates after March 1, 1900 (which seems not including that date, but this is a detail…). But we should not digress. The real issue is that if you try to call the DATE function passing values between January 1 and February 28, 1900, you will see a different day as a result. evaluate row ( "x", DATE( 1900, 1, 1 ) ) -- return WRONG result -- [x] 12/31/1899 12:00:00 AM   evaluate row ( "x", DATE( 1901, 2, 29 ) ) -- return WRONG result -- [x] 2/28/1900 12:00:00 AM   evaluate row ( "x", DATE( 1900, 3, 1 ) ) -- return CORRECT result -- [x] 3/1/1900 12:00:00 AM As usual, this is not a bug. It is “by design”. The DATE function works in this way in Excel. And also in Excel it was “by design”. In this case the design is having the same bug of Lotus 1-2-3 that handled 1900 a leap year, even though it isn’t. The first release of Lotus 1-2-3 is dated 1983. I hope many of my readers are younger than that. I tried to open a bug in Connect. Please vote it. I would like if Microsoft changed this type of items from “by design” (as we can expect) to “by genetic disease”. Or by “historical respect”, in order to be more politically correct.

  • Firefox does not print flash content

    - by Rochelle
    I am using Firefox 3.6.15 on a Windows 7 Professional, 64-bit Operating System, Intel Core i7 CPU, 3.33GHz, 10BG RAM, by Hewlett-Packard. Firefox does not print flash content, aka swf objects, nor does it show them in the print preview pane...I want to print out the entire web page with the flash content. I seem to only be able to see flash and html content together in print preview and to print in IE8. I have tried to google this issue, but could not find a solution. I was trying to print preview/print out the following site: http://www.discovertheponds.com/. Flash content will display in print preview and print in IE8, but neither print preview or print in Firefox. I have also updated the Java on my computer to the most recent update, and ran the firefox plug-in checker at http://www.mozilla.com/en-US/plugincheck/ . I do run Firebug and Web Developer, but have currently disabled them. Is this problem on my end, meaning some issue with my computer...or is this because of how the website was programmed in HTML/Flash...or is this a bug with Firefox? I am a website designer and am also concerned that others will not be able print sites I develop or have already developed that have flash content from Firefox. I used to think Firefox was better than IE at everything. What happened here? Was it some change in Firefox's version that caused this problem?

  • External microphone not working

    - by haireefairee
    gnome-volume-control does not recognise external hardware. My headphones work nonetheless, but an external microphone does not. External microphones used to work, but at times were temperamental - I would have to login or logout with or without microphone plugged in. I am running Ubuntu 10.04 LTS (Lucid Lynx) on an mSi U100 wind notebook with one Intel soundcard and trying to use a jack microphone which has worked previously. USB microphones have also been problematic. I have done the basics: Installed upgrades. Checked nothing is muted. Looked for the device on gnome-volume-control. Tried using a different microphone that works on a friends computer. Tested my microphone works when using a different computer. Checked my soundcard can be seen (cat /proc/asound/cards). I have done more complicated things: I have tried playing around with settings in alsamixer. Nothing is muted. I can adjust "mic" and "internal mic" regardless of whether an external microphone is plugged in. I have the choice of input source from "mic", "front mic", "line" and "CD". I've played around changing this and it hasn't helped. I only have one CAPTURE option. In gnome-sound-recorder I have the choice of line, microphone 1 and microphone 2. I have played around changing this option. None of these pick up sound from the external microphone. Microphone 2 is the microphone on my laptop which is bad quality. In gnome-sound-recorder I have the choice of different profiles, and changing this has not helped either. I have looked at gstreamer-properties but none of that seemed helpful. I don't know if there a way to check if these external devices are being picked up. I would like to make an external microphone work. Please help!

  • If not gamedev, what do I do !

    - by brainydexter
    Hi, I am a game dev who was working in the game-industry and then..got laid off. Ever since then, life couldn't get less stressful! During this time, I have met so many other devs who have also been laid off irrespective of the number of years they have been in the game. Now, the problem really gets worse, since I am not a US citizen (yes, I am in US) , and am on an international visa here, I might have to soon pack my bags and go back to my native country. Going back is not bad at all, apart from the fact, that gamedev is still in a very nascent stage there. There just aren't many opportunities. So, employment is the key to maintain a valid visa status. After giving it a lot of thought, I am thinking of staying away from gamedev jobs for the time being, given its job unstablity. This brings me to my current problem. I can't think of a domain/place where I can use my game development skills. I know graphics/simulation/visualization is huge, but I can't think straight and am left clueless where to go from here. What are some of the domains/companies where I can use my skills ? I'd appreciate any insight on this (and I apologize if this is not the place to post this kind of a question).

  • KDE not loading without nomode tag in grub and bad resolution [migrated]

    - by fcole90
    I recently installed Linux Mint 13 KDE but it's not working fine. At first I had to use failsafe mode to boot because normal boot takes to a textual login. If I use normal boot and text login I'm not able to run KDE nor with kdm start neither with startx. kdm says that's already running. Instead X is not able to run because can't connect Xserver to display. If I stop kdm and starx again doesn't change anything. Now I edited the grub to load in nomode. In that way KDE loads but resolution is wrong and xrandr doesn't help, because if I do this: cvt 1366 768 it changes it to 1368: # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync I also installed bumblebee and nvidia drivers because of optimus technology.. It worked just to have fun with glxspheres but there isn't any gain on KDE..

  • Not Happy With the Monochrome Visual Studio 11 Beta UI

    - by Ken Cox [MVP]
    I can’t wait for a third-party to come out with tools to return some colour to the flat, monochrome look of Visual Studio 11 (beta). What bugs me most are the icons. I feel like a newbie when I have to squint and analyze the shape of icons on the debugging toolbar just to get the one I want. (Fortunately, the meddlers didn’t mess with the keyboard commands so I’m not totally lost.) Not sure what usability studies told MS that bland is better. Maybe it is for most people, but not for me.  Gray, shades of gray and black. Ugh. And don’t get me started on the stupidity of using all-caps for window titles. Who approved that? I see that there’s a UserVoice poll on the topic (http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2623017-add-some-color-to-visual-studio-11-beta) but I doubt that anything will change Microsoft’s opinion in time for the release. Once a product gets to a stable beta, most non-crashing stuff gets pushed to the next version. I hope I’m proved wrong. Fortunately, Visual Studio is quite customizable. Unless ‘Bland’ is hard-coded, some registry tweaks and a collection of replacement icons should allow dissenters like me back to productivity. BTW, other than hating the UI, VS 11 beta is working quite well for me on a .NET 4 project.Note: Although my username for the ASP.NET domain includes the letters "[MVP]", I'm no longer an MVP. Apparently it's nearly impossible to change a username in the system. My apologies for the misleading identifier but I tried to have it changed without success.

  • Google earth will not reinstall

    I was trying to perform the the fix found at this link http://www.omgubuntu.co.uk/2012/01/how-to-make-google-earth-look-native-in-ubuntu It requires you to delete certain files from the /opt/google/earth/free folder and then add some new ones that you download. I deleted the files but the links to download the new ones were unusable. I was using gksudo nautilus so trash was disabled meaning I could not restore the files I had deleted.

  • To write or not to write: Frameworks [closed]

    - by caarlos0
    Today some friends and I started discussing frameworks.. Some of us strongly believe that in 99.9% of cases, writing a new framework is a bad idea. We believe that probably some of the millions of frameworks out there should fit our problem, and if not, some hack, API, or configuration should be enough. If not, we think that contributing to some framework, suggest features or something like that should be the best solution. The 0.1% is when none of the frameworks fit to our case. But, some of us say that it is better to have an "internal corporate framework" (for example), because it's faster to fix issues, creates a 100% fit with the app, because of the "learning" factor (when you improve your skills building a framework), etc. I think that to go out coding frameworks like there's no tomorrow is not the right way. I've seen a lot of small teams building their own framework just to spread the word: "we built our own framework, we rule, bro". Generally, the framework is crap, without any documentation, and only works for their own applications. Opinions are opinions, devs are devs, without the intention to start any kind of flame war, I ask: What do you think about that? What parameters you consider when building a framework? What do you think about all this?

  • Loading a new instance of a class through XML not working quite right

    - by Thegluestickman
    I'm having trouble with XML and XNA. I want to be able to load weapon settings through XML to make my weapons easier to make and to have less code in the actual project file. So I started out making a basic XML document, something to just assign variables with. But no matter what I changed it gave me a new error every time. The code below gives me a "XML element 'Tag' not found", I added and it started to say the variables weren't found. What I wanted to do in the XML file as well, was load a texture for the file too. So I created a static class to hold my texture values, then in the Texture tag of my XML document I would set it to that instance too. I think that's were the problems are occuring because that's where the "XML element 'Tag' not found" error is pointing me too. My XML document: <XnaContent> <Asset Type="ConversationEngine.Weapon"> <weaponStrength>0</weaponStrength> <damageModifiers>0</damageModifiers> <speed>0</speed> <magicDefense>0</magicDefense> <description>0</description> <identifier>0</identifier> <weaponTexture>LoadWeaponTextures.ironSword</weaponTexture> </Asset> </XnaContent> My Class to load the weapon XML: public static class LoadWeaponXML { static Weapon Weapons; public static Weapon WeaponLoad(ContentManager content, int id) { Weapons = content.Load<Weapon>(@"Weapons/" + id); return Weapons; } } public static class LoadWeaponTextures { public static Texture2D ironSword; public static void TextureLoad(ContentManager content) { ironSword = content.Load<Texture2D>("Sword"); } } I'm not entirely sure if you can load textures through XML, but any help would be greatly appreciated.

  • ScreenManagement better practices ?! Textbox not focusing

    - by xykudyax
    I saw a question here using DataTemplates with WPF for ScreenManagement, I was curious and I gave it a try I think the ideia is amazing and very clean. Though I'm new to WPF and I read a lot of times that almost everything should be made in XAML and very little should be "coded behind". My questions resolves about using the datatemplate ideia, WHERE should the code that calls the transitions be? where should I define which commands are avaiable in which screens. For example: [ScreenA] Commands: Pressing B - Goes to state B Pressing ESC - Exits [ScreenB] Commands: Pressing A - Goes to state A Pressing SPACE - Exits where do I define the keyEventHandlers? and where do I call the next screen? I'm doing this as an hobby for learning and "if you are learning, better learn it right" :) Thank you for your time. Yes the Q/A I was talking is: What's a good way to handle game screen management in WPF? What I've done so far was to create a Screen class (derived from UserControl) and create some virtual methods: - one for Initializing stuff (like focus a given component by default) - another for inputHandling I handle it by using a switch case and by listening to the PreviewKeyDown event from the parent container (MainWindow) Im not able to do it another way! Help?!. - and a finally one that removes the keyEvent method (when the screen is terminated) Parent.PreviewKeyDown -= OnKeyDown; am I doing okay? I face a problem. When I add a new screen (userControl) containing a TextBox I'm not able to give it autofocus :/ The Caret is there but is not blinking and I have to hit "TAB" before being able to input anything at all :/

  • early audio offset in Audacity and VLC, but not Banshee

    - by reek
    I'm editing audio files with speech in Audacity, marking particular types of speech. I just noticed that files edited in Windows have different intervals marked than files edited in Ubuntu. After testing and confirming this error, it seems that the audio playback in Ubuntu clips the sound too early from the end (early offset), which causes the person doing the editing to mark the interval wrongly. Interestingly, the error appears in Audacity and VLC (which I sometimes use for playback), but NOT Banshee. Since both Audacity and VLC have this problem, I assume it is not application-specific. I don't know why Banshee handles this without problem though... Are there any ALSA or Pulseaudio settings that are likely to cause this problem (I know very little about either)? The task itself does not appear to consume large amounts of resources, but I am on an old laptop, so here are my specs: Ubuntu 11.10. Dell XPS m1210 1.6 GHz Intel Core, 2 x 512 Mb 667 MHz RAM, Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01). Audacity settings: Device Interface: ALSA (cannot select anything else)

  • libgdx game not disposing

    - by Yesh
    My game does not exit entirely even after calling dispose() method. It loads a black screen when I launch it for the second time and works well if I kill the game manually and restart it. I get an error that says buffer not allocated with newUnsafeByteBuffer or already disposed when I try to dispose off the SpriteBatch object. This is were I suspect the problem to be. But not able to fix it entirely. Please help! Here is how I have built it (I have put the sample code here just to show you guys that there are no visible loop backs in dispose function, please correct me if I'm wrong)- In game screen, public void dispose() { AssetLoader.dispose(); render.dispose(); Gdx.app.exit(); } Under class AssetLoader- public void dispose(){ Texture.dispose(); sound.dispose(); } Under game render class - public void dispose(){ spritebatch.dispose(); //throws an error when I GameScreen.dispose is called font.dispose(); shaperender.dispose(); } I believe that my spritebatch isn't disposing which is causing the black screen but I cannot find a way to dispose it off successfully. Any help would be greatly appreciated.
