I updated to the kernel 6.1 and I am happy that now the audio on my laptop works properly. Granted just 2 speakers out of 4, but soon the fix will land in the kernel 6.2 so that all of the speakers will work. Also it fixed the issue with my screen brightness - when I lowered it to the max low I could not bring it up again. Now works! Finally it fixed the issue with closing the lid. Now it respects the settings I have for that, such as suspend, hibernate, lock, whatever.

Also, changing some stuff in the BIOS as suggested on some arch forums, makes the hibernation kinda work....but idk. I don't use that anyway.

All in all, everything works on this laptop, except 2 speakers for which a fix was already pushed so should be fixed soon, and the hibernation may not be perfect. How awesome! Thank you Linux and thank you to everyone who contributes to the open source software universe.
