I have this problem too.
It happens with any mp3 player or listening to an icecast stream, but 
not with mplayer when looking at a divx. I looked at the irqs, and have 
uhci2 and my pcm0 on the same irq. However, this problems occurs only 
after 3 or 4 hours of uptime, generally.
Should I try to change my irqs ? and if positive, how do I do this ? in 
the bios ? (note : I have also uhci1 on the same irq than vr0, and it 
makes my computer crash at the end of the shutdown, when using the GDM 
to shutdown)
