Hello, I have problems using Mic+ with volumio, and with raspbian too, on a Raspberry Pi 2.
It can only produce a sort of white noise with something in the background. Merci les gars.
Hi Androne and welcome;
If this is not working on both Volumio and Raspbian you might have a hardware issue. Try to disconnect any other hats than Mic+, Check that all 40 header pins are well soldered and make a good contact with the female connector of the Mic+, if possible try on another raspberry pi.
if all that fails please ask a replacement thru Amazon.
Kind regards;
