The issue will possibly affect sound on any or all Lenovo Legion Gen 8 and 9.
The obvious difference in dmesg on my Legion Pro 7 Gen 8 (16ARX8H) on
6.12.5, is the following line is completely missing:
[ 4.761665] snd_hda_codec_realtek hdaudioC1D0: bound
i2c-TIAS2781:00 (ops tas2781_hda_comp_ops
[snd_hda_scodec_tas2781_i2c])
This suggests the TI amplifier is never identified.
(A second issue is LenovoLegionLinux DKMS not loading at all as of
6.12.5. I believe this is a separate issue, but it could be related to
how that project detects laptop models. Mentioning it here for
completeness.)
