So I finally figured out what was going on with my audio on my GoPro Hero5. One clip I would have audio and the next I wouldn’t. I first thought it was some setting wrong in the camera. Nope that is not it. Then I played with the little GoPro mic adapter and bingo. The cord on the adapter had a short in it. I now have a new one and we are back in business. Thank goodness that was really messing me up and losing my audio.
