I have done additional testing on older kernels. I tried: 5.11.16, 5.12.13, 5.13.13, 5.14.15, 5.15.13, 5.16.16, 5.17.9, 5.18.15, 5.19.12, 6.0.12, 6.1.12, 6.2.12, 6.3.9 . The error message is the same in all cases: gem300@opensuse15dot6:~> sudo dmesg | grep snd_hda [sudo] password for root: [ 7.152649] snd_hda_intel 0000:07:00.1: enabling device (0000 -> 0002) [ 7.152777] snd_hda_intel 0000:07:00.1: Handle vga_switcheroo audio client [ 7.152914] snd_hda_intel 0000:07:00.6: enabling device (0000 -> 0002) [ 7.157150] snd_hda_intel 0000:07:00.6: no codecs found!
