I upgraded my system and all microphones stopped working. Before that I had loaded custom UCM configs to make my microphone working.
Upgrades which can be related to the issue:
After OS upgrade I loaded again all latests UCM configs from the repo. I also tried older which I had but the error is the same.
First issue:
alsaucm reload;
ALSA lib parser.c:2021:(parse_master_file) Incompatible syntax 6 in HDA-Intel.conf
ALSA lib main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -22
alsaucm: error failed to open sound card hw:0: Invalid argument
I fixed it by changing syntax from 6 to 4 in HDA-Intel.conf. It worked for me before OS upgrade.
Next issue:
$ alsaucm reload;
ALSA lib parser.c:243:(error_node) UCM is not supported for this HDA model (HDA NVidia at 0xfc080000 irq 130)
ALSA lib main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6

I tried to disable HDA Nvidia module from loading by adding snd_hda_codec_hdmi to /etc/modprobe.d/blacklist.conf but it didn't work.
How to solve this issue? I don't need audio through HDMI. It would be nice to have it working without any hacks but disabling it is enough for me. Can I somehow disable HDA Nvidia in UCM?
I can't downgrade Nvidia driver because I need that.
