So this just confirms what I somehow saw above - pcm1 is input only, so
for producing sound, setting hw.snd.default_unit=1 is not going to help.

Also, I am not sure, but this line, from your verbose output above

pcm0: Playback channel matrix is: 2.0 (disconnected)

may explain why you are getting no sound. On my Yoga Book, with working
sound, I have

pcm1: Playback channel matrix is: 2.0 (unknown)

definitely different.

I think it is really easy - connect your HDMI monitor, and you should
see new device in 'cat /dev/sndstat' output, probably pcm2. Then, with
setting hw.snd.default_unit=2, you should get sound from HDMI monitor
speaker(s).
