I had a sequence completed. Part of the sequence was a nested sequence that contained several ProRes clips. It was playing perfectly.
I saved the sequence, closed Premiere and opened the sequence 30 seconds later.
The Prores sequence audio tracks now show no waveforms. They are not muted, they are just flat-lined.
If I double click on the original source ProRes clips in the bin, the exact ones that don't show any audio in the sequence's timeline, the audio plays just fine.
The other parts of the sequence (other than the nested ProRes sequence) play their audio just fine.
I'm perplexed. I didn't do anything to kill the audio for these clips in the nested sequence, and have no idea how to restore it???
