I lied. Apparently I found few logic errors within VIA driver itself.
Before you continue, would you replace your
/usr/src/sys/dev/sound/pci/via8233.c with this one:

http://people.freebsd.org/~ariff/test/via8233.c

Then..

# kenv -u hint.pcm.0.via_dxs_disables
# kenv -u hint.pcm.0.via_dxs_channels
# kenv -u hint.pcm.0.via_sgd_channels
# kldload snd_via8233 ; kldload snd_via8233
# sysctl hw.snd.pcm0.vchans=0
# sysctl hw.snd.maxautovchans=0
# sysctl hw.snd.slave_enabled=1
