Voiceover Recording Problem
I am working on about 20 movies. This problem is on only 1 of them so far. I have used the microphone to place many short audio clips onto the movies. On this one movie new audio clips do not play sound. There is no ducking checked on any of the files. Volume is high. The recording sound bar acts normally. Sound waves look normal when examined. I can record on other movies and play the sound back. What is happening here? Is there a hidden mute control that I might have accidentally hit? Is this file corrupted? Thank you for any help.
