alsa-ucm-conf 1.2.5 broke front headphone output on pipewire-pulse

[amezin]

After upgrade to 1.2.5, front headphone output isn't working.
In GNOME Settings, when I select front headphone output and click "Test", it shows a dialog with text "Click a speaker to test", but there are no buttons to click.

systemctl --user status pipewire shows this:

Downgrading alsa-ucm-conf to 1.2.4 fixes the issue

Tried pipewire 0.3.29 and pipewire git master
Though with pulseaudio 14.2 the output works
Motherboard: ASUS ROG Strix TRX40-E

With alsa-ucm-conf 1.2.4 - output working:
alsa-info.sh output: alsa-info-good.txt
pw-dump output: pw-dump-good.txt

With alsa-ucm-conf 1.2.5 - output not working:
alsa-info.sh output: alsa-info-bad.txt
pw-dump output: pw-dump-bad.txt

git bisect points to 1e6297b as first bad commit

I'm on Arch Linux, they backport alsa-project/alsa-lib@ddfc32a , alsa-project/alsa-lib@0e4ba2e , alsa-project/alsa-lib@9621d0b to alsa-lib 1.2.5: https://github.com/archlinux/svntogit-packages/blob/46eb11ee65a863a532d15dba8fe408e469b2696b/trunk/PKGBUILD#L15-L17

Upgrading alsa-lib to the current master branch alsa-project/alsa-lib@abe805e does not solve the issue
