I have a BPI Zero M2 and I cannot make the Adafruit MAX98357A mono amp work (https://learn.adafruit.com/adafruit-max98357-i2s-class-d-mono-amp/raspberry-pi-wiring). I have successfully used it in a RPI 4 and it works perfectly. I connected it to the same pins as I did with RPI and also using the same configuration, but there’s no way I can make it work.
Is there any steps that I need to customised to make it work with a BPI ?
EDIT: I think the problem stems on the fact that the BPI Raspbian distribution doesn’t have the snd_soc_rpi_simple_soundcard module (or something similar). Is there anyway to get it somewhere?
