I also have K7S8X motherboard and I'm having problems with sound. I'm on Mandrake 10.1 and a bit more lucky because sound is played properly by applications, but the sound from my microphone is very poor quality and would like to know how to get it work normally (all is OK in Windows). Perhaps I don't have the proper driver. I would also appreciate help in getting Linux to work well with this soundcard.

yea just for the record, sound works fine in Windows. That's I'm thinking it's a driver problem. Maybe alsa doesn't support this sound device yet. We would just have to confirm w/ other ppl who have this motherboard as well.

Another problem I have - the mixer controls don't work as they should... I've read someone's experience with this motherboard that Suse installs audio drivers for SiS7012 and that the sound works very well and the mixer too. I wonder if installing this driver (http://www.sis.com/support/driver/linux.htm) would help, I wanted to try but I'm a novice in Linux and have no idea how to install this stuff, especially that it is supposedly for Redhat, so might not work on other distributions...

I tried Knoppix 3.7 and it was even worse than Mandrake, I could hear the sound but no recording was possible - audacity shouted that the sound device could not be found. I wonder if there's any solution other than getting a different motherboard. Or perhaps installing some cheap sound card that we know is supported by Linux would be much easier than trying to find the proper driver?
