"NO Sound from One Camera But Second one works fine"에 답변This happened to a second camera. I got it to pick up again by pushing the mic into the body. I suppose maybe a connection is loose or faulty. Don’t have time to open it up now to check it out, but give that a try. This camera had the same problem before, and IIRC, I had to do something similar. Wiggling didn’t help mine at all. Hope this helps!
