alsa-project/alsa-ucm-conf issue #685 was opened from Xeltalliv:

Updating from v1.2.15.1 to v1.2.15.2 broke sound on ASUS Zenbook 14 UM425UA laptop. It has no external headphone jacks.
I narrowed it down the cause to the commit https://github.com/alsa-project/alsa-ucm-conf/commit/c8b55418ff36036fc960731191ae0922bf6f1dae
With v1.2.15.1 `wpctl status` shows:
```

Not sure if any of the following helps:
In both cases `dmesg | grep -iE 'snd|alsa|pipewire'` shows:
