No sound on headphones BOM-WXX9-PCB-B2

[BasilYes]

I'm on nixos (may be it's related)

What I done.

• Install kernel patch from #28 to kernel 6.9.7
• enable options, change blacklist and add modules
• change alsamixer settings
• get ucm and ucm2 from https://github.com/codepayne/alsa-ucm-conf

Speakers work perfect, microphone work perfect (inside my headphones).

Headphones have no sound by default, but if I plug jack halfway when it's not detected in system but still get signals, headphones audio start work with speakers. If I enable speakers in alsamixer when headphones plugged in and enabled inside pavucontrol, speakers start to work but no sound on headphones.

Here pavucontrol screenshots

When headphones plugged in (no sound in headphones)

When headphones half way plugged in (sound in speakers and headphones)

Tested with aplay and VLC (so it's not pipewire config issue I think) Sorry for my English, Thanks for your work!

Alsamixer see audio card on 6.9.7 without patch, but in paucontrol I have dummy output (even with ucm) With 6.8.12 with and without patch no sound at all (no audio card in alsamixer / aplay -l)
