realtek_revers_patch

In attachments alsa-info and journalctl grepped with 'hda|realtek|cirrus'
with revert - with reverting commits for patch_realtek (patch i'm using for that in attachment). Mic is working
without revert - just as it should be with the latest kernel. Mic doesn't work.

I suppose this bug is the same as https://bugzilla.kernel.org/show_bug.cgi?id=219158
??

Not exactly.
There are 2 issues with sound:
1. Issue with sort_r function which is related to kernels 6.9 and higher.
2. Issue with patch_realtek.c which is related to kernels 6.12.2 and higher.

219158 was open due to 1st issue and it was resolved. After that it was closed (because the original issue (1st) was resolved)
It mentioned 2nd issue in the discussion, but there wasn't work to resolve 2nd bug.

Current bug (219743) was opened due to 2nd issue.

Could you then point exact which commit *started* breaking?

[   10.377731] input: HD-Audio Generic Mic as /devices/pci0000:00/0000:00:08.1/0000:65:00.6/sound/card2/input53
[   10.377776] input: HD-Audio Generic Mic as /devices/pci0000:00/0000:00:08.1/0000:65:00.6/sound/card2/input54

I think this was assigned same input device name for Mic. It maybe needs to change verb table for 0x19 and 0x1b.

Please test this patch.

Please do "echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef"  Before do alsa-info.sh 
Then please do alsa-info.sh again.

I suppose this is it - https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e3ea2757c312e51bbf62ebc434a6f7df1e3a201f (they all kinda connected to it).

Done. Patch didn't help, also I can assure you that this pins fixups are correct.
In the archive in attachments (alsa-info_dump_coef_par) 3 alsa-info outputs (all with parameter dump_coef) with your patch, without patches and with reverting commits from my 1st message (mic work only in this one).

I check the dump file. You disabled power save mode.
Test attach patch maybe it helps.
