How can I mute the audio in a saved edited file? I've adjusted audio before but something has changed. I'm using TVsuite 4 Rel 646a. I open the Tools>Adjust Audio and move the volume slider all the way to the left (-96 dB) and then click Close. The audio graph indicates that the audio is gone for the entire edit session but when I Save it and re-load the "edited" file, the audio is right back! What am I doing wrong?
