Im fairly new to Premiere and haven't really encountered this problem before. I used a Nikon E4200 to create this video and when I play back the audio the sound cuts out where I've highlighted the track. If anybody could help me figure out what this means it would be greatly appreciated. thanks.
Try and drag in just the audio track into the timeline from the source monitor. (Re- Open the clip in the source monitor then use the Speaker Icon)
Drag it on top of the existing ( overlay it) or onto a new track then trun off the old track (or delete that audio - alt--click >del).
