A quick follow-up on this, one of the reporters of:
https://bugzilla.kernel.org/show_bug.cgi?id=206289

Still has a problem with the internal mic not working.

He has tried both using all 4 of these:

hda-verb /dev/snd/hwC1D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774
hda-verb /dev/snd/hwC1D0 0x20 0x500 0x45
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x5289

As well as just using:

hda-verb /dev/snd/hwC1D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774

Which some users report is enough for them.
His exact modelis "UX533FTC-A8221R"

Still the 2 / 4 commands (depending on the
exact model) do help for various other users/models
so it would be good to get these added as fixups to
the kernel.

The specific model with the internal-mic issue
will need further examination.

Hans
