Can you guys with snd_via8233 driver try these patches?

http://staff.mybsd.org.my/skywizard/FreeBSD/sound/via8233.c.diff
http://staff.mybsd.org.my/skywizard/FreeBSD/sound/vchan.c.diff

set your hw.snd.maxautovchans or hw.snd.pcm0.vchans appropriately, add
hint.pcm.0.via_dxs_disabled=3D"1" into your /boot/device.hints and
possibly with option PREEMPTION in kernel.
