We are currently working on a project to use a Pi Zero, an IR camera, and the Raspiaudio Mic+ for building a Smart Door Bell.
Therefore I got a Mic+ from a friend. It worked fine, but we had problems with the speaker output being recorded by the mic. Therefore we decided to move the microphone further away from the speaker as it is suggested by the Installation Guide (MIC+ installation guide). However, for some reason, the microphone did not work anymore after this step. Because we thought it is probably our fault because we were not careful enough in breaking apart the microphone we ordered a new one. In the case of the new one, we were extremely careful in removing the mic. However, still the same problem no microphone voice can be recorded.
We took a look at the hardware, and it looked perfect, so all connections and electronics looked fine (we also tested the connection with a multimeter). Thus, we thought about a Software issue, although it was working nicely with the non-removed mic of the first board. So we freshly set up the PiZero to test for Software issues and tested several configurations. However, still, we were not able to record anything…
So my question is: Has anyone experienced similar issues? Is it actually possible to remove the mic, so did anyone managed to do that? Is there something that we might have misconfigured? Or did we just have bad luck with our hardware?
