I have seen the repeating audio bug at the end of videos after rendering and know that Adobe is working on this. My issues are a bit different and all began with the most recent release:
1. I am using the Dynamic Link to import an AE comp into PP. With the new release, I am getting multiple instances where the programs will not open, requiring restarting my computer.
2. Audio clips are repeating at various points in the PP sequence, not just at the end. Re-importing the AE comp into PP fixes the issue only temporarily. The duplicated audio and "stuttering" is evident in the PP preview, so the issue is not due to the rendering process and therefore will not be fixed using alternative render methods.
Is anyone else having this issue?
This issue is fixed in the After Effects CC 2015.3 (13.8.1) bug-fix update. This update, available now, can be installed using the Creative Cloud desktop application, or by choosing Help > Updates inside any Adobe application.
