SND_HDA_* excrept from kernel config

On PCI device discovery the Intel HDA codec doesn't bind to appropriate codec (if that is the correct term). The device codec (Conexant) is loaded, but sound doesn't work. Reloading the main module (snd_hda_intel) fixes the issue:

5.15.29, have observed it already at least on 5.10.27, HW is ThinkPad x201 (x220 as well). I'm marking it as regression, since it used to work in the distant past (5.4-ish at least iirc)

Note that the used by counter for both snd_hda_codec_conexant and snd_hda_codec_generic got increased after reloading snd_hda_intel.
Comment 2 Takashi Iwai 2022-03-28 12:07:36 UTC
Could you try to bisect?  At least it'd be helpful to know which kernel release starts showing that problem.

Will try, but it's going to take a while.

In the meantime, any suggestions where this could go wrong on the system configuration side (i.e. PEBKAC)?

Honestly speaking, I have no idea.  As the module probe succeeds, it might be outside the sound driver itself but in a deeper level.
