@Mitchell, Also I have a problem with the microphone. The recording is blank, although it is being detected by the “arecord -l” command. Can you check the overlay if it is fine or not? Because I bought a brand new INMP441 microphone and soldered its pins, and still the recording is completely blank, either by “arecord” or by using “sounddevice” library in Python. If you can check it and let me know, I would be grateful.
