There is no sound output over HDMI. This includes sound over USB-C devices as
well.

When I conduct a speaker test on an available HDMI device here are the results:

> speaker-test -c2 -l5 -twav -D hdmi:CARD=PCH,DEV=0

speaker-test 1.2.9

Playback device is hdmi:CARD=PCH,DEV=0

I am hoping I can help provide information to work out the sound issue. Not
sure if it is an openSUSE issue, a Kernel issue, lack of support for the 13th
Gen Intel or maybe something else. I am not interested in using any other
distro so I would rather just do what I can to help work through the problem.
