FWIW, openSUSE Leap 15.3 kernel is based on 5.3 but got tons of backports, hence its HD-audio part is almost equivalent with 5.13 or later kernel (except for the recently changed mute-LED handling -- which must be irrelevant with your problem). The above indicates that the codec is detected and set up. The rest part is often some vendor-specific quirks. For that, details are missing completely. At best please give alsa-info.sh output (run the script with --no-upload and attach the output). > Kernel 5.13.10 or 5.14-rc6 say: > > calling azx_driver_init+0x0/0x20 @ 1 > snd_hda_intel 0000:00:1f.3: enabling device (0000 -> 0002) > snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops) > snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: last cmd=0x200f0000 > snd_hda_intel 0000:00:1f.3: No response from codec, disabling MSI: last cmd=0x200f0000 > snd_hda_intel 0000:00:1f.3: Codec #2 probe error; disabling it... > snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to single_cmd mode: last cmd=0x000f0001 > hdaudio hdaudioC0D0: no AFG or MFG node found > snd_hda_intel 0000:00:1f.3: no codecs initialized If it's the result from the more-or-less similar configuration like the previous Leap kernel (regarding the audio), this must come from another part than the sound driver, likely either PCI or arch/x86. You might need to bisect for that... thanks, Takashi
