Using Premier Elemnts 15 with Windows 10. I have created a slide show with music background, but want to add narration over the music. (I have an exterior mic) I need to be able to listen to the music while I'm narrating, but if I mute audio, I can't hear the music...if I un-mute it, I get feedback. I've tried muting it on the Windows Volume Mixer...muting the voice element on the Premier Elements Audio mixer...but no matter what I do, I either hear no music and my narration, or music with horrible feedback from my narration. I know I'm doing something wrong, but can't figure out what...Help!
