Hmm is right, and Google isn't helping me out either. That can sometimes mean that nobody is having any trouble with it at all.
I searched around, and based on various tidbits of information I could find:
- People seem to have it working with ALSA. Maybe try it with ALSA
- There are a few updates to the via82cxxx_audio driver since your 2.4.20 kernel. Maybe try upgrading to the latest kernel.
- This guy seems to have gotten it to work; too bad he doesn't say how. I suppose you could e-mail him: http://www.opensound.com/cgi-bin/oss...splay=threaded
- There are different drivers for your compiling pleasure here: http://www.viaarena.com/?PageID=294
Maybe one of those will help.
