Comment 13 for bug 315824

Hey dude:

Try this series of commands to stop/restart sound:

  killall pulseaudio
  sudo alsa force-reload
  pulseaudio -D

I put them in a handy little script called "fixalsa.sh".

Doesn't exactly *fix* the problem, but at least I don't have to reboot every
time.

Good luck!

Brian
