LinuxQuestions.org - Upgraded to 2.6.10 kernel and now sound doesn't work

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:

Code:

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