Thank you!

You are the kind of smart people that are pleasant to work with ;-)

It's easy:

grep -i -C6 spdif /proc/asound/card0/codec\#0
grep -i -C6 'stereo digital' /proc/asound/card0/codec\#0

And check the connectivity between pin complex and audio output nodes.

Thanks for the clarification. I failed to figure out by reading the code
why codec#1 is silently ignored, hence the brute force print-and-reset hack.

Now you can do a 'cat /proc/asound/card0/codec\#1' and read about the
HDMI codec. For it to work, you may need the bleeding edge Xorg drivers.

So let's create a new model?

Thank you,
