[AudioI] Defective PI zero audio hat?

[Matt]

Hi the information looks correct w.r.t. alsa-info and the mixer settings 
for microphone capture. It is possible that the polarity of the 
microphone is assembled incorrectly.

If you set the alsamixer to record from line inputs and they are 
enabled, then I assume it should work.

How are you recording ? arecord ?
