I have been experiencing the same thing tonight. Bought I still had Logic PRO running in the background. Once shut that done and went back to AE, the first playing of the RAM Preview played fast. Then the rest have been correct. So I believe you are right about another program accessing the audio processor. Once AE is the sole controller the audio plays fine.

Thanks to Creative Cow and all of you who contribute here. Without this thread I’m sure I would be pulling what’s left of my hair out in the next hour or so.
