No sound 12.1

HELP please.
Upgraded from 11.4 and had all the versions from 10.1 seems like years ago. Never had problems with sound. Did new install with 12.1 and have no sound whatsoever. Followed a few online guides but nothing works, I am not a code master so things need to be spelt out.
Here are some screen shots of my system.

If you need anything else, let me know.

Keep it simple keep it safe.

I recommend you install the application pulse audio volume control (pavucontrol) and use that to control your volume. There are some examples in my blog post here: Pulseaudio Basics for openSUSE with pavucontrol - Blogs - openSUSE Forums
