I have 2 Speaker pHat boards and am using them on 2 different Rapsberry Pi Zero W
I installed the code from here https://github.com/pimoroni/speaker-phat as instructed using the command -
curl -sS https://get.pimoroni.com/speakerphat | bash
That worked OK as far as I know, it asked to reboot the Pi at the end of the installation.
I went to “/home/pi/Pimoroni/speakerphat/test” and ran test.sh … and was massively underwhelmed by the resulting sound output / volume :-( It is barely audible and according to “alsamixer” the volume is set to 100.
I have tried both speaker boards but both are the same :-(
