Hello.
I have the above stack (see Title). I use arecord and capture an output.wav file. I copy the file to the pc and try and use windows media player to play it but nothing comes from it....The signal is a microphone coming into the 3.5mm jack and I monitor it on the 0.100" spaced pin connector and can see strong (2V level) signal. When I capture it on the pi and use sox I get (which are the settings I used). Can someone tell me why there is no audio?? I have also captured multiple files and tried to play them over a JBL speaker that is connected to the pi but to no avail
