cat /proc/asound/cards and make sure that is happy.
The best thing to run is alsamixer. If you don't have it, install this
http://www.mirror.ac.uk/sites/download.fedora.redhat.com/pub/fedora/linux/core/development/i386/Fedora/RPMS/alsa-utils-1.0.3-2.i386.rpm
M mutes/unmutes, arrow up and down changes level, arrow right and left moves
between channels.

Doesn't look good. I guess you can fiddle with the onboard peripheral / IRQ
mappings in the BIOS if you have that option, maybe try a kernel commandline
param like acpi=noirq

This might be worth fiddling with, using option in /etc/modprobe.conf maybe.
