The mute button started behaving differently. Now it seems to be creating keyframes that toggle the audio and off during playback. And these keyframes aren't visible. I assume this is a setting I need to turn off? Hugely frustrating and screwing up my entire audio that was nearly done. argh
I replied to your other post about this. But also make sure that in your Audio Track Mixer panel that your tracks are set to READ and not to Latch, Touch, or to Write. When those are on it will set mute keyframes every time you toggle the mute button.
