Hi,

what does 'cat /dev/sndstat' show? It should be just small excerpt from
the above, but still...

HDA setup is a bit of mystery for me, I have GPD MicroPC where I am not
able to produce any sound using internal speaker, recently found Yoga
Book working with both internal speaker and output line out of the box.

For the former, I have a workaround, kind of - when I connect
additional monitor via HDMI port, I am able to route sound to that
monitor just by setting hw.snd.default_unit=2. It is not the best
solution, it just work well enough for me.

Regards,
Milan
