Funny thing, I have seen the same behavior on my mom's windows thing.
It was a interrupt problem...
I have noticed that when the sound is broken, the interrupts does not
count any longer too.

Don't think so. The machine runs 24/7. No powercycles, just a simple
reboot now and then. (to get that darn music back. My old machine ran
for years without other reboots than kernel upgrades. Even my
girlfriends windows2000 runs more stable!)

Initially I used the sound system on the motherboard, now its a PCI thing.
mogul@linuxine:/proc/asound$ cat cards

Looks like irq25, and alone there.

I will give it a shot. (think I have tried at least one of them before... )

Hmm, thats not an option. Only got one PCI slot in there.
