I am struggling a bit with a newly received µMoth. It is basicaly just giving noise and not recording via the microphone it seems. At first, I thought it was noisy power supplies via USB but it looks the same when powered by a LiPo battery:

I tested both recording to SD card powered via USB, Live with the USB mic firmware (both with the Audiomoth Live app and other real time spectrogram apps) and also recording to SD card powered by LiPo battery. Any ideas?
