Since alsa-utils 1.2.5 alsactl will print messages to standard error if the HDA model does not support UCM. Apparently, this is intended by upstream and users should manually disable UCM if they don't want to see these messages. See https://github.com/alsa-project/alsa-lib/issues/159#issuecomment-862441961
