This is a bit unfortunate, since the driver tend to handle all kind of
hardwares and codecs generously without specific bias on certain
vendors. The good part about it is that it has "special" guarantee
that at least will ensure that all playback path are laid out
properly. Things like this (especially the parser) can be refactored
and improved in near future.

How about this one: replace your sys/dev/sound/pci/hda/hdac.c and
sys/dev/sound/pci/hda/hdac_private.h with:

http://people.freebsd.org/~ariff/test/hdac_stac9220_wesley.c (hdac.c)
http://people.freebsd.org/~ariff/test/hdac_private.h
