More details are needed for detail answer.
you can setrecord.verbose: truefor checking your mic works properly. But before that, you should confirm there was any other error to issue. Check your error log. -
@sean arecord: main:788: audio open error: Device or resource busy and where is my error log?

@citizendevpi
Your system seems not properly configured to use audio device. that might be not the issue of module itself.
And you can see the log withpm2 log mm #or your registered process name for MagicMirroror
stoppm2thennpm start devin your MM directory. -
@citizendevpi
Anyway,
You should confirm to check your audio device card and name, and your RPI should be able to run below commands (or similar)arecord -d 5 test.wavor
arecord --device plughw:1,0 -d 5 test.wav(
plughw:1,0might be different. You should find your proper device card and number witharecord -l) -

arecord --device plughw:1,0 -d 5 test.wav
That works? If so, you can set your config
record.device: "plughw:1,0", -
