From a neofetch output:
Kubuntu 22.04.4 LTS x86_64, kernel 6.5.0-21-generic.

Also I will skim through the sites linked by you, but Im afraid that suggested ALSA dont work properly (or stable) with 7.1 surround.
According to Schwarzer Kater hint, here's my hardware probe results:

(Hope that this isn't temporary link, never been there)

Welcome.

Which version of Kubuntu do you use (link)?

Sometimes one can get an idea of what is missing/required by searching this database for one's exact (laptop) model: https://linux-hardware.org/

I'd start here. It's from Arch Linux, but their Help Pages are about as good as you can get. Oh, and welcome to KFN!

Hi, Im currently fighting with audio drivers on my machine. Amazed by KDE Plasma, I decided to switch from plain Debian to Kubuntu hopefully that I wont approach another drivers and kernel problems, and yet still there is some pain I kinda see myself as newbie to Ubuntu-based distros, so it would be lovely to hear as much info (and hints) as possible.
