Description:
After upgrading alsa-ucm-conf from 1.2.3-2 to 1.2.4-1, pulseaudio is no longer able to initialize my sound card (ALC3204). It falls back to Dummy Output instead. It generates the following error:

Failed to find a working profile.
Failed to load module "module-alsa-card" (argument: "device_id="1" name="pci-0000_03_00.6" card_name="alsa_card.pci-0000_03_00.6" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no card_properties="module-udev-detect.discovered=1""): initialization failed.

Additional info:
All pulseaudio and alsa system configuration files are package defaults.
The output of pacmd list-sinks with alsa-ucm-conf rolled back is attached, as well as the journal containing the error.
This system is a Dell Inspiron 7405 2-in-1 with a Ryzen 7 4700U and onboard graphics.

Steps to reproduce:
Obtain an up-to-date Arch Linux system with an ALC3204 sound card. Onboard audio should not work.
Rollback alsa-ucm-conf to 1.2.3-2. Audio should now work.

I have a ALC245 on a HP Envy x360 with 4700u which also is experiencing sound output issues after the upgrade except I'm using pipewire. The symptom seems to be that any application with audio cannot get the right sink. I would need to use the pavucontrol applet to select the manually select the proper device.

I've also noticed that alsa-lib-1.2.4-2 is again flagged as out of date so there's hope that a proper fix is coming?

This seems to be deteriorating, as even choosing the right sink outputs now has no sound even though pavucontrol seem to think there is a signal going to the choosen subsystem. Going to see if I can roll back to a known good state. I hope this does not completely messed up the audio subsystem....
