there's most likely an irq conflict... and you can't share an irq
between pci and isa devices... use pnpdump to see the range of irq and
io address...

in my case, i use irq 7... i have to go into bios and reserved irq 7
for isa devices... and load parport with irq=none(parallel port gives
up its default irq 7, and uses polling mode instead), and put the line
in /etc/modules except setting irq to 7.

this is on the intel se440bx motherboard...

imo, it's probably easier to simply disable the onboard sound and go
with a cheap pci based soundcard, instead of wasting so much time
