I have been onto Adobe support but they dont have a solution. I am trying to add narration, the speaker is feeding back with my own voice a short time after I speak. I bought a new Rode mic on USB but although slightly better, the speakers are still feeding back. I have turned volume right down and also speakers off but it makes no difference.
I am no expert but surely the Mute Audio whilst recording button should do the job, Adobe say they dont control the speakers in the app.
