Description of problem:
Anytime I try to play music, the sound starts fine and then fizzles out and stops working.  I noticed it first with flash stuff, but figured it was just flash, but I just tried to play a cd using Audacious (with the PulseAudio output plugin selected), and I got the same problem.
