Ok I managed to get back onto 5.15.x,
still no sound options available other than "Sortie fictive" (Fake output). - my OS is in French language.

Meanwhile, I've tried 3rd party made in china asmedia asm1083 pcix soundcard, it crashes the system after 5 seconds of playing sound. as soon as sound started, crash. Removed the soundcard, no more crashing. This happened with 6.2 kernel, I tried many kernels.

Now I'm on 5.15.0-84-generic (assembled this new computer for my daughter) and with the Rx series video cards (I have 3 of them, 6500xt, 6700xt, 6800xt, no sound when used with the MSI b550 chipset motherboard.

On an older AM3 motherboard that my son has there is sound but I'm not sure if it's the AC97 chipset or the hdmi doing the sound on that computer which is working, haven't checked that.

This MSI B550 running AMD Ryzen 5500 has no sound.

I've ordered a sound blaster audigy card now, hopefully better luck than the knockoff card that claimed to be linux ready.
