alsa-project/alsa-ucm-conf issue #384 was opened from motomyslen:

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: - `alsa-ucm-conf:all 1.2.6.3-1ubuntu1.4 1.2.6.3-1ubuntu1.9` - `nvidia-driver-510:amd64 510.108.03-0ubuntu0.22.04.1 525.147.05-0ubuntu0.22.04.1`

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 alsaucm: error failed to open sound card hw:0: No such device or address ``` 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.
