I have fitted a new Wolfson Audio board to an compatible Raspberry Pi V1 - ( bd rev2)
and downloaded on to the SD boot card the Wolfson image
It boots up and goes to the bespoke desktop.
I can record using the 2 on board microphones but cannot get either of the two external inputs (line in and headset microphone to record anything.
I am using "arecord" after running the appropriate record shell "use case scripts " executable.
I have checked continuity of the P5 connector and all OK
Has any one suggestions as to what I need to do to get an external microphone to work?
