When I play any video on Ubuntu 9.10, volume is not there. Is it lacking a package?

why dont you use the latest version 10.10? I think that would be the ultimate solution. – Gaurav Butola Nov 17 '10 at 13:22

If you don't have sound when playing a video, here's some general advice:

  • Assume the simplest cause and work from there.
  • Does it depend on that video? Can you play a simple sound file (like one from this page) If the WAV file plays fine, it might be related to a missing audio codec, or to your media player application.
  • Is the volume up - both PCM and Master volume, if that applies to your case - and the sound not muted? You can check that by right-clicking on the volume meter in your systray.
  • Is your stereo properly connected and set up, no headphones plugged in?
  • Does sound work on another operating system?

If these do not point to a cause of the problem, it might very well be a driver problem. In that case you should:

  • Find out if your sound card was detected at all;
  • Use a more full-featured mixer program, such as alsamixer, and see if changing the settings has any effect;
  • Find out your audio chipset. This can be done by running lspci in the terminal and watching out for what loooks like a sound card;
  • Google that sound card, or the driver used for it. In some cases, adding a module option can bring the sound card to life.

If it is indeed a driver issue, it might help to check if the card works under Ubuntu 10.10 - you can verify this easily by using live media such as a CD or a USB stick.

Do you have the alsa-* package installed ?

Try with:

dpkg -l |grep alsa

if you cant upgrade to 10.10, try these:

sudo apt-get install ubuntu-restricted-extras package

sudo /usr/share/doc/libdvdread4/

sudo apt-get install gstreamer0.10-ffmpeg gstreamer0.10-pitfdll gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse libdvdnav4 libdvdread4 libxine1-ffmpeg

ubc@ubc-desktop:~$ dpkg -l |grep alsasudo apt-get install ubuntu-restricted-extras package grep: apt-get: No such file or directory grep: install: No such file or directory grep: ubuntu-restricted-extras: No such file or directory grep: package: No such file or directory ubc@ubc-desktop:~$ its give some error when i use the given command – shalu Nov 18 '10 at 4:46
@shalu: there is a small mistake in your command. dpkg -l |grep alsa and sudo apt-get install ubuntu-restricted-extras are two different commands and need to execute one by one. just run the above three commands one by one. you will be fine – aneeshep Nov 18 '10 at 5:31

If you're having problems with sound, click the Volume applet, then Sound Preferences, and check your Volume, Hardware, Input, and Output settings. If that fails, see
