Hi folks !

Here is my question, related to sound.
My problem is that when I have more than 2 days of uptime, I experience
distorsions in the sound when I hear music, when I play games, or watch
films, and even if the load is at 0.16
More surprising (and maybe related, but it is another question), mplayer
tells me that my computer is actually too slow to watch a film (I have
an Athlon XP2400+, 1GB DDR and my disk has 2 GB free)
 
But today, something more weird appeared (here is the dmesg) :

Interrupt storm detected on "irq12: pcm0 uhci2"; throttling interrupt
source
pcm0:play:4: play interrupt timeout, channel dead
pcm0:play:4: play interrupt timeout, channel dead
pcm0:play:4: play interrupt timeout, channel dead
pcm0:play:4: play interrupt timeout, channel dead
pcm0:play:4: play interrupt timeout, channel dead

I had formerly launched xmms, but it was on pause, and no music was
playing. I only have a mouse on usb, and I didn't move it when that
crash.

it's not that new, but I cannot remember having seen a problem like that
on current@freebsd, I suppose it's not related to a too old version...
(or I hope so)

Best regards,

Grégory
