Ok, Google comes through again. http://www.signalground.com/article/3140544956 Fair use excerpt: "Linux Performance and Compatibility The two distributions that I am currently using for compatibility testing are RedHat 6.2 and Caldera OpenLinux eDesktop 2.4. Both Linux loads were pain-free and worked on the VIA based designs without any glitches. The only problems encountered involved the embedded audio. Both distributions seemed to recognize the embedded audio during installation, but neither was able to make it work correctly. Looking at the included Soyo Driver disk, there were some VIASOUND drivers included for both the Caldera and RedHat distros (these were the only distros supported). Unfortunately, these drivers were already compiled for older versions of both the RedHat (6.0 and 6.1) and Caldera 2.2. No source files were included, so we were unable to recompile the drivers for the most recent distributions. Even some low level hacking to try and get these older drivers to work yielded nothing functional. We are currently talking to Soyo to lend some input into getting the audio source files included on the driver disks. VIA states on their website that they don't currently support Linux, but are currently developing drivers and plan to support it in the future. Let's hope this situation improves soon." Rats! This mb is cheap and fast but the sound is a real problem, as it seems to interfere with pci sound cards as well. I'm going to try some more things before screaming!
