Sound issues with Panasonic Toughbook CF-19 Mk8

Hello, last time I resolved this issue, I was using OpenSUSE 13.2 and, yes that is half a decade ago and I do think I wrote a little about it at the forums but for the love of God I can’t seem to find it anywhere.

So, hardware is fine, Windows 10 shows everything works well. on Kernel 6 on TW, display is fine, touchscreen is fine but I cannot get it to make a sound. On W10 the speaker is un-muted (this was an issue on the 13.2, I had to make sure that the speaker was unmuted to be able to make sound on 13.2) and I do remember writing a short script to make the sound to work on boot, that installation is long gone and I don’t have the slighted idea what it was.

Any suggestions?
