Question How do I switch sound drivers?

Well I've been messing with this for about 2 days now and still can't decide if I'm doing something wrong or if it just isn't going to work.. but the sound system isn't working and I've been trying to change drivers.

I'm running MDK 8.1 and the install slapped in the CS46xx drivers, which obviously aren't the right drivers for my sound chip (this is a laptop BTW). The error I get suggested that I try the CS4232 drivers, so that's what I've been trying to accomplish.

I have modified the modules.conf file and replaced the driver it specifies there.. when I restart the sound module, I get an error that says invalid IO, IRQ and DMA params AND the module is reporting no such device.. I also get this exact error when I use modprobe. SO ... at this point I figure I need to specify those params. Well I've been able to find the IRQ address from the respective file in the /proc directory, but for the life of me can't find an IO address or DMA...

I guess my question here is, do I reallly need to specify these parameters, or should the module just have found it the first time if it was going to work? (assuming I'm doing this all correctly). If I do need to specify these params, then how the heck do I find the IO and DMA addresses? I've searched through all the files in the /proc directory and the hwconf file produced by kudzu, and can find nothing suitable. Maybe it's just the wrong driver... any ideas???

A very stumped individual........

Have you tried turning off pnp-os in your mother board bios?

This is on a laptop... but to answer your question, unfortunetly the BIOS on this computer is not that complex. If you're familiar with Thinkpad's, you'll know what I mean.
