This audio design is a bit different from sof-hda-dsp, the dmic is on a standalone sound card. Please see the alsa-info.txt:

And that's an interesting case. Can we manage multiple cards in a single UCM profile?
Takashi
I am not much familiar with UCM files creation. As per my understanding, UCM entries will program the mixer controls depending up on the use case and selected device.
UCM is more than that. It manages which PCM device is chosen, which jack control corresponds, etc, too.
Takashi
Got it. Could you help us to get the UCM file which will work for both sound
cards for our platform.
