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 alsa-info: http://alsa-project.org/db/?f=0c4d6f062e6065d47ee944f5953f0aaa328d4b44 -- Eliot
