Audio Waveforms not showing in Multicam Clips

Did a quick search here and did Render --> Audio but I still don't see waveforms. My multicam sequence settings are multichannel mono mapped to 7 channels...trying to insert interview clips in a non-multicam standard timeline. Not sure if I have to change my audio settings on my timeline but would like to see all waveforms...I see waveforms when I drop clip as un-nested but would rather match frame back to the synced audio rather than the source audio.
