Realtek ALC285 audio kernel fix not working for me?

Asked by Bertilak

I have a Lenono laptop using Intel HD Audio and a Realtek ALC287 audio codec which produces a lot of digital noise through the headphone output.

The command "sudo hda-verb /dev/snd/hwC0D0 0x1d SET_PIN_WIDGET_CONTROL 0x0" fixes it, so it's the same issue described in this bug: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1809856

which is also described here https://patchwork.kernel<email address hidden>/

It appears that it was patched here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/pci/hda/patch_realtek.c?h=linux-5.15.y#n6906
which is included in subsequent versions.

I am on kernel 5.15.0-73-generic but I also updated to v6.1.32 and the problem remains, inless I execute the hds-verb command myself.
I am on Mint Vera based on Jammy

Should this be working based on the kernel patch I found, or is it another problem with the fix not being enabled somehow?
