Hi,

I am using a K7VTA3 motherboard with a VIA Technologies, Inc. VT8233 AC97 Audio Controller (rev 50) (according to lspci). The distribution I am currently using is Redhat 8.0 which does not support that sound chip. In a mailing list I found a pointer to your project and downloaded driver, library, utilities version 0.9.0rc7. I compiled and installed them according to the information I found at http://www.alsa-project.org/alsa-doc/doc-php/template.php3?company=VIA&card=&chip=via8233a&module=via82xx.

After using alsamixer and unmuting the sound, I could hear something. I can play wave or mpeg files and KDE is playing also funny sounds but unfortunatly the music and sounds are sourrounded by crackling noise in the background. Using Bills operating system the sound works ok, so I think it is not a board or wiring problem.

I wonder if somebody has made the same experience, and what a workaround or fix may be for this problem.

It would be great if someone could help me with the configuration. Thanks!

Frank
