Have a look at /etc/modprobe.d/sound. You can use options for then
module when loaded. "modinfo snd-intel8x0" will show you a list of
availible options.

alias snd-card-0 snd-intel8x0
options snd-intel8x0 index=0 id=i810 buggy_irq=1

You can also just use /etc/modules to load it with the propper options
at startup.

snd-intel8x0 index=0 id=i810 buggy_irq=1

Another thing to try is to make a custom kernel with some of the
sound/alsa modules compiled _in_ (as opposit to use modules). This
sometimes solves problems on certain hardware. But leave at least
snd-intel as module.

I think there has been a bugreport about intel8x0 for the kernel.
This should be solved with IIRC 2.6.12/13. Have a look at the
changelogs (ftp.kernel.org / mirror) - this may/may not have to do 
with your problem.

Funny. Maybe something got loaded twice. Have you already tried to
rmmod all the sndmodules and do "/etc/init.d/alsa restart"?
