yep, got exactly the same issue with mine. Started happening after swapping the mic to the other side for a flight. I unplugged the mic again and reinserted it which solved the problem for a couple of flights but it recently happened again. Definitely seems to be an issue with the mic attachment as I think it is triggered by moving the mic boom. I’m not flying much at the moment but will investigate further when I can. Keep us updated if you get it sorted.
