[Cialug] Tracking down an audio problem

[David Champion]

I've had similar issues, it's usually an issue with pulseaudio, for
starters try "service pulseaudio restart". It can also be corrupt pulse
config files.

Linux and audio have always been interesting... between alsa and pulse and
whatever, have never seen one that's really bulletproof.
