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 commit a963fe6d0eb6ef0a15b3aade7c186cd5bb7bd01f Author: Callum Osmotherly callum.osmotherly@gmail.com Date: Thu Sep 15 22:36:08 2022 +0930

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.
It's been already reverted in the upstream, commit 417b9c51f597.
And FWIW, the backport for that patch is already in the queue for the next 5.15.y release:
