Ubuntu 11.10

My speakers have stopped working - no sound is coming out.
The headphone port is also not working.

When I plug in headphones now, no "jack plugged in" alert is popping up anymore.
I can adjust and mute the sound via buttons and sound settings, but it doesn't affect the playback.

A few weeks ago, this happened a few times, and I was able to fix the sound by muting/unmuting the sound a few times and increasing/decreasing the volume, but now it will not work.

Steps I have taken:

$ sudo apt-get install ubuntu-desktop

worked for me after restarting.

Note: My keyboard shortcuts were reset as a result, and my touchpad didn't work for one boot cycle, but it all works perfectly for me now. I hope this command can help someone else!
