snd_via8233 problems on 5.4-STABLE WAS: Re: CMI9761 soundchip

Loading snd_via8233 afterwards by hand works, though. The only thing I then get in /var/log/messages is: pcm0: <VIA VT8237> port 0xd000-0xd0ff irq 22 at device 17.5 on pci0 pcm0: <Unknown AC97 Codec (id = 0x434d4983)> (this is ASRock K7UPGRADE-880/A/ASR-Board) Patches eg to snd_via8233 are welcome :-) Regards, Holger
