Upgraded to 2.6.10 kernel and now sound doesn't work


I was using the default 2.4.31 kernel with Slack 10.2. Now, when I boot, I get the error "FATAL: Module via82cxxx_audio not found." When I was choosing what modules to compile, I chose the snd-via82xx modules, and never saw a via82cxxx_audio one. I have a Soyo KT600 Dragon Plus v1.0 motherboard with onboard VIA AC97 sound. When I try to play any sound, the first half second of the song plays over and over. I tried modprobing snd-via82xx, the module loads, but I still have the same problem when I try to play anything. I don't really know what to do, so any help is appreciated.

You don't say how you upgraded your kernel. I'm too old and tired to play 20 questions. Issue and read "man alsa" and read this Kernel Rebuild Guide and I guarantee answers are in those two documents.

This is some VIA VT82XX info:

NB: That is for kernel 2.6.16.9, but yours should be the same.

Did you try running "alsaconf" to configure ALSA anew? And then ran "alsactl store" to save those settings across a reboot?

After upgrading the kernel you also have to upgrade alsa as it was compiled against the old kernel. The alsa modules from testing have always worked for me when using 2.6.* kernels.
