OK Here is the best solution I discovered for me for this multi cam audio popping. First edit in your multi cam clip to the time line. Then lower its audio track to 0db. Then edit just the audio of the best camera angle audio on an additional audio track below the multi cam audio track at the same in point of your multi track. Since it is on its own track it will not be affected by the multi cam cuts. This also allows you to put audio effects on it as well.
I hope this works for you.
