Audio Pre-render/Render Issues

Hi All,

I make a lot of car spots at work using Mostly AE and Premiere. The projects are pretty graphics heavy and then usually have a voice over or a spokesmen green screened on. I usually make the graphics for the spot before I get to VO and then I will just tweak the timing to match the VO once it is imported. The issue I have been having for a while now is that once the audio is imported AE has a really hard time pre-rendering at full speed and it always plays back super warped sounding like it is in slow motion. after the audio is in the timeline I never get green pre-render bars again and it takes way longer than it should to export out of AE or from the media encoder. these are 15 second spots and I get stuck trying to guestimate timing of graphics and audio in the timeline and then my exports take like an hour to render. I know it isn't an issue with the graphics because my payback and render times fine without these VO. I also have no problem play audio back in premier either it is only ever in AE.

The standard size of the VO are between 1MB - 3MB

PLEASE HELP IT WILL SAVE ME SO MUCH TIME!!

Side note. every time I export the colors change and look way desaturated. they are fine in the timeline but way different in the export. maybe someone can point me to a quick solution for this. if not i will create another post with more detail later.
