Reverting the following patch seems to fix it for me in linux-next 20250314: Author: Olivier Moysan Date: Thu Mar 6 18:18:40 2025 +0100 ASoC: dmic: add regulator support Allow management of the regulator that may be used to supply the digital microphone. Signed-off-by: Olivier Moysan Link: https://patch.msgid.link/20250306171840.593443-3-olivier.moysan@foss.st.com Signed-off-by: Mark Brown linux-next 20250307 worked. Later versions had the problem I described above. For the bisection I used the default .config from Debian's 6.12.x kernel when building. I build and ran them on my Samsung Galaxy Book. This device got a patch recently in linux-next not related to audio. That's why I wanted to test linux-next and found this.
