Still no sound for me after upgrading to 8-stable. I've booted Ubuntu
livecd and (surprise!) the sounds works, both playback and recording.
I've downloaded latest alsa-driver-1.0.24 sources, and apparently, they
do quite some magic in alsa-kernel/pci/hda/patch_sigmatel.c:
1) my sound card (8384:7690) is reported as STAC9220 on FreeBSD, but
ALSA code lists it as STAC9200; -- can that be a problem?
2) my codec seems reference one, and ALSA applies the following pin
configuration (in addition to other things):
static unsigned int ref9200_pin_configs[8] = {
0x01c47010, 0x01447010, 0x0221401f, 0x01114010,
0x02a19020, 0x01a19021, 0x90100140, 0x01813122,
};
These values vaguely match what I see from our snd_hda(4), but I am
not sure how to properly apply them via device hints. Before I dig
deeply into the guts, maybe someone knowledgeable can provide my with some
guidance while I'm still on the "river bank"?

In addition to the above, contents of Linux' /proc/asound/card0/ files
is available here:
