Restarting fixed it. Thanks a lot!!!!

As of PP 8.2 (2014) I solved this issue by muting all the audio tracks in the nest that I wasn’t using. I assume that PP has difficulty passing the waveform of multiple tracks to the sequence in which it’s nested.

So turn off all the audio in the nested track that you don’t want to see in the editing sequence.

It all has to do with keeping the tracks and their waveforms panned to separate channels.

After being thwarted by this missing multicam sequence waveform problem for years, I finally lucked into a solution for this that seems to solve the issue every time.

I was working hard to make sure that all of the audio tracks in my final sequence (which included many multi-cam sequences with 3-5 second system audio tracks — lav, lav, lav, lav, boom) could be exported as independent channels for a final mix. This led me back to the multicam sequences where I would pan everything left and right to keep them independent and then route each pair to a set of channels, 1&2, 3&4, etc.

Bingo, waveforms reappeared instantly in every sequence that the multicam sequence is in. It makes sense when you think about it. The waveforms are created on import for each mono or stereo channel. And then if you have them panned center in your multiclip sequence when you nest that into another sequence you are mixing the channels on each track and Premiere would need to create a new waveform to show the two mixed together (which is why you get a waveform when you render the audio into a new placeholder file), but if you keep the files panned to separate channels in the track mixer in your multicam sequence, then when you edit that into a new sequence it can just inherit the waveforms because they haven’t been melded together.

This also explains why muting some tracks would bring waveforms back. If everything was panned center and mixing together, then no inherited waveforms will appear, but if only one track is unmuted/solo’ed and is still panned center that’s fine because the waveform is not changed by any other channels, so the new sequence can inherit it without Premiere needing to render new waveforms. Basically, Premiere won’t create new waveforms for the mixed channels unless you tell it to render a new placeholder audio file, so we need to keep the channels mixed to left and right in each channel pair to maintain waveform integrity.

Hope this works for some other people. It sure took away one of my major gripes with Premiere when I figured this out, and also highlighted the power of their track and clip audio settings (which are far more vast than this little tidbit). Now, if only they could sort out the match frame to master clip for subclips.
