Resetting User Configuration

For some reason, pulseaudio's user configuration files can become corrupt(unsynced?) in some way, and deleting them (and forcing fresh ones to be generated) fixes a no sound condition. After using the command below, log out/in.

Ubuntu 12.10/Quantal (and earlier)

rm -r ~/.pulse*; pulseaudio -k

You can give a try to command line interface for your sounds settings, if GUI doesn't work for you..

  • Install gnome-alsamixer (open terminal CTRL+ALT+T then execute following command):

    sudo apt-get install gnome-alsamixer
  • Run gnome-alsamixer:


    on the same terminal AlsaMixer will be opened.

  • Use -> or <- arrow keys to change the options. Up and down arrow keys to increase/decrease volumes. M key to Mute. Press Esc to exit.

Hope this short description helps you any how. Reply if something goes wrong.
