Hello sound system maintainers,
a recent patch to the stable 5.15 linux branch unfortunately introduced
a regression. From 5.15.71 onward (also in 5.19.15) plugging in an
external headset into the audio jack no longer results in a working
microphone. Symptoms are that there is no choice to set the connected
device to microphone only (I am using GNOME, so once you plugin a device
you get a dialogue to choose it's type, normally there are 3 choices,
Headphone, Headset and Microphone, with the bug the last one is
missing), and the connected microphone no longer records any audio. Note
that you can still choose the headset microphone as audio input, it just
does not record anything.
Doing a git bisect I was able to identify the commit introducing this
regression:
a963fe6d0eb6ef0a15b3aade7c186cd5bb7bd01f is the first bad commit

ALSA: hda/realtek: Enable 4-speaker output Dell Precision 5530 laptop
commit 1885ff13d4c42910b37a0e3f7c2f182520f4eed1 upstream.
Just as with the 5570 (and the other Dell laptops), this enables the two
subwoofer speakers on the Dell Precision 5530 together with the main
ones, significantly increasing the audio quality. I've tested this
myself on a 5530 and can confirm it's working as expected.

Which makes sense, since I noticed this regression on a Dell Precision
5530 laptop.
Downstream bug report: https://bugs.gentoo.org/876843
Please revert this commit to restore the previous working condition on
all affected branches, since an external headset is a very common use
case with these kinds of laptops. There were similar commits for
different laptop models, but I do not have any of these models, so I
cannot say if they cause a similar regression.
Best regards,
Jan Henke
