Linux - how to disable onboard AC97 sound so my other sound card works?

[Skinner2]

I just installed Mandrake 8.2 (love it!) and in the control center -> hardware I have to items under soundcards and one is VIA AC97 on board sound, but I also have a
SB128 card that I would rather use. I just can't figure out how to disable the on board sound. Any suggestions?

Thanks!

Oh ya, I'm using Gnome right now...

If a module is getting loaded for that sound device, stop it from loading up. If support for it is built into the kernel, compile a new kernel without support for that sound chipset.

Uhhh, I wish I wasn't such a newb at this...cuz then I'd know how to do what you said

I'm searching the net as we speak!

first off, make sure its disabled in your bios. then, find out what module is used for your onboard audio. go into /etc/modules and comment it out with a # sign. find out what module your sound card uses, and add a line to /etc/modules that lists it. should work.

btw, its just a SB 128, how big of an improvement could that possibly be over onboard audio? just a thought

WOOHOO!! I love it when something works!

Thanks BingBong, I disabled it in the BIOS and that cured it.

I hear that! Actually it is quite an improvement because UT was continually freezing on me and I knew it was that stupid onboard sound so I went out and got the only card I could at that time, which was an SB128.
Also when I would listen to MP3s and do little things like open up Internet Explorer or load basically anything it would cause the song to skip. I finally got fed up...

Thanks again for your help
