Why wouldn't you cut the power AND the signal? That MEMS microphone is producing analog output, is it not? I did a cursory search for the printed part numbers but came up empty handed.

It looks like an analog part, yes, going to an ADC.

Sure, cutting both would be even better.

But-- as I posted earlier-- recovering a signal from a depowered MEMS device would be somewhat miraculous. https://news.ycombinator.com/item?id=25743822
