Every now and then I happen to get my sound to stop working in Ubuntu 11.10. Sometimes this occurs when suspending and then resuming but most recently it stopped after switching the sound output from my laptop to an HDMI port. Here's a quick way to fix this without restarting.
Open a terminal (ctrl+alt+t) and type:
sudo /sbin/alsa force-reload
Enter your password and it'll reload the ALSA sound drivers (see below). Now go back into the sound settings and everything should work!
