Public bug reported:
ian@tqft-l:~$ lsb_release -rd
Description: Ubuntu 11.10
Release: 11.10
Expected sound to work.
What happens - sound fails randomly.
Playing flash video typically, but other sound as well.
Sound stops - for no apparent reason but sometimes when I manually
adjust the volume.
Look in Sound preferences - no hardware.
Reboot machine, hardware is there under sound preferences and sound
plays for a bit. Then it fails and hardware is showing under Sound
Preferences.
Checked AlsaMixer hardware is there. Pulse audio crashing - tried
restarting it (sudo service pulseaudio restart) but no change.
