try to add dxs_support=3 to snd-via82xx module option.
(or dxs_support=2 if it doesn't solve the problem.)

see alsa-kernel/Documentation/ALSA-Configuration.txt for details.

btw, before building the alsa-driver externally, it's better to remove
CONFIG_SND* in your kernel configuration
(/usr/src/linux/include/linux/autoconf.h).
otherwise there might be inconsistencies.
