sound card detection AC97

[myrrdex]

Ok, i know there have been posts about the AC97 sound card but mine is more of a quality issue.
I used windows to listen to a song that has abit of bass but had the base turned down and it sounded fine. but when i go into linux and run the same file in xmms the speakers sound like they are busted or something. they have a scratchy/muffled sound when the bass line comes in. i figured my sound card wasn't configured correctly so i went into /usr/sbin/ and ran soundcardconfig and sure enough it said it doesn't support ac97 sound card. So i have a default configuration? because i can here sounds just fine but i guess they sounds are on the lowest possible quality for my sound card or something? can some one tell me how to make knoppix recognize my AC97 sound card?

Type cat /proc/pci and see if you can find your soundcard. I also experience that sound via xmms is not that perfect. Meaby trying a different output plugin can improve sound (ctrl + v).
