UPDATE: (maybe this is a Premiere issue?)
I tried a few times to replicate my procedure to troubleshoot, and it seems like the stage in which the audio goes silent is in the export from After Effects CS6 to Premiere Pro. I can see all the audio layers, but they don't play in the timeline. They do, however, play in the preview window. Any ideas?
I started making an After Effects project, then realized that with 50+ audio layers, I really need to work with Audition. It is easy to bring one layer (track) into Audition, but the only way I could devise to get all layers in the correct place in the timeline was via Premiere Pro. When I went from AE to PPro to Audition, all tracks are visible, but only one is audible. I'm totally new to Audition (and an ancient AE user) and really would appreciate some help. Thanks so much!
