Consider adding snd-mixer-oss to your /etc/modules file. These are
loaded per default on boot.

I had this problem on my ppc machine because the correct modules
were not loaded. By adding them to /etc/modules, the problem
was corrected.

Hopefully I won't be telling you anything you don't already know:
If you have the isapnptools package installed, you should have the
command-line tools isapnp(8) and pnpdump(8)available. pnpdump(8)
provides you with a listing of PNP devices in your machine somewhat
akin to /proc/isapnp. By saving pnpdump's output to a file, you have a
pretty handy isapnp configuration file which you can edit and modify
with any text editor - making sure you enable the device and change
(if necessary) it's IRQ's and memory to something the machine can work
with. See the manpages for more information.
hope this helps,
Elizabeth
