Hello everybody,
I recently purchased an Adafruit I2S MEMS Mikrofon Breakout - SPH0645LM4H and want to use this with my Raspberry Pi Zero 2".
I followed this instruction and tried many other things as well:
https://learn.adafruit.com/adafruit-i2s ... iring-test
However, when I try to record something the volume always stays a 00% (see attachments).
In my /boot/firmware/boot.txt i added/changed the following lines (and tried some other internet suggestions, all without any results):
dtparam=i2s=on
dtoverlay=googlevoicehat-soundcard
Looking into the alsamixer, changing the volume/boost as suggested in the tutorial also didn't change anything.
Do you have any idea, what I am missing or what I am doing wrong?
Any help is much appreciated!
