Comment 64 for bug 352732

Hey, guys. I have a few workarounds for this, and they're quite simple, so rejoice!

The first one is SUPER easy. just sudo gedit ~/.xinitrc and add this line:

amixer -c 0 sset Master,0 100%

Now, even though you still have the muting problem, your pc will run this command on boot to unmute it. Easy as pie.

There is another, more complicated way to do this as well. The above only works if you have a normal Linux startup session, e.g. GNOME. If your startup session is, say, XBMC, as mine was, that solution won't work. You have to go to further lengths, that is, disabling PulseAudio altogether. <a href="http://idyllictux.wordpress.com/2009/04/21/ubuntu-904-jaunty-keeping-the-beast-pulseaudio-at-bay/">This blog post</a> details how to go about this. It's still pretty easy, just unnecessary if the simple command above works for you.

Good luck!
