Sure thing. I tried to give a lot fo machine info in my first 2 Emails,
sorry that I missed some.
Reading that page, the good news is that sound output works with the
same 6.5.0-14.generic kernel under ubuntu 23, so at least linux can make
it work without windows needed.

looks like alsa-info mostly gathered what I had captured manually and
posted, but here it is

I added the modprobe.conf debugging recommended in your page, and that
seems to have killed sound:
