I have been working on a project in CS5, sent the project to En from Pr. When I play the project on the timeline in En, everything is peachy, however when I preview the project there is no audio whatsoever. Same story with flash exported files. This is just now happening, I have exported and revised the project multiple times, only changing minor details in graphics through Pr. I havent messed with the audio at all, it is mostly native audio and 1 .mp3.
I am working on a MacPro with plenty of RAM and processing speed. Any ideas? I am finally finished with this project and would like to get it out of house!
