[SOLVED] ALSA: failed to import hw:0 use case configuration -2

ALSA: failed to import hw:0 use case configuration -2

I have stored the configuration for my sound card in an asound.state file and alsactl is reading it fine, but during boot and whenever I try running the command manually, this message appears in the log:

alsa-lib ../../../git/src/ucm/main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2

I don't understand what is going wrong and I haven't found much online. Any ideas for how I could fix this error or what might be the origin of it?

This is what I get if I run aplay -l:

~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: mycard [mycard], device 0: 44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi [44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Thank you.

Solution

After some more investigation, I've found this command that has removed the error message:

alsactl --no-ucm restore

Adding that --no-ucm part has fixed it, so the problem was probably that my sound card doesn't support UCM.
