I'm having the same playback problem on a few Multicam projects I'm working on. When playing through the timeline, the audio briefly drops every second or two. It's not an issue with the original files (I've tried them in other software) and I haven't applied any unusual settings to the audio. It doesn't seem to make a difference if one track or several are playing simultaneously. I have created proxies, and the video is playing fine at Preview(Full) quality. Is this a common problem and/or an easy fix? Thanks!
