Yeah, the mic wont pick up input without it. I did have a feeling that
it's supposed to be set up automatically rather than being set as a
verb but I couldn't figure out which part of the code I'm supposed to
modify to make that happen. I've tried running it with dynamic
debugging turned on but I don't see the output of codec_dbg from
alc_headset_mode_ctia() :(

Will do, thanks.

I added the model name string to make debugging easier for users. When
troubleshooting this issue, I followed many guides that recommended
the 'Codec-Specific Models' document, but no entry existed for the
ALC287. I thought that adding a model name would help users quickly
identify and apply the correct quirk without needing kernel expertise.
However, if this goes against the current standards, I’m happy to
adjust.
