Can you briefly explain how to confirm that this specific problem
exists, and what info you would need from me to add a new machine?


I have a Lenovo E14 Gen 2 with AMD that claims to have DMIC but no
evidence of it working.

My workaround so far has been blacklisting the related modules...
blacklist snd-soc-dmic
blacklist snd-acp3x-rn
blacklist snd-acp3x-pdm-dma
