Hey all. I just purchased a Videomic pro from a friend. I can guarantee that it was working when he shipped it to me, no sketchiness in our deal or anything. The last time it worked it was being used on a Sony A7SII I believe. When I plug it into my GH4 I see a level meter but I get no sound. My in camera audio settings seem to be okay to me. I plugged it into my macbook pro to see, and my mac does not recognize the mic at all. The batteries are good, it powers on with a green light. It does not work on any of the possible built in setting configurations. Any ideas what could be wrong with it?
