Too few details here so i can only guess, but make sure that the timeline is set to 48000 Hz and that your recorded audio is 48000 Hz and export to 48000 Hz as well. Mixing sample rates/bit depths of the audio can lead to similar issues.
Use Adobe Audition to convert from let´s say 96000 Hz to 48000 Hz. Look for Convert Sample Type of just load the file/s and press F11.
did you add any effects to the audio tracks?
Premiere frequently can't handle that... it can't handle audio effects from within it's own program, and the export will be out of sync where the playback is fine... Adobe is too busy developing their next new program that no one needs, or asked for, to solve this or any of the other bugs that exist in their programs that people actually use.
Thank you Jim.
I will try this if Averdahls way doesn't work but there are quite a few to check so it would be labour intensive.
Yes I added a few but nothing major. This would be terrible from Adobe if it cannot handle it.
Yes you are correct. I think i need to convert mine from 96000 Hz to the 48000 Hz. I'll give it a go and fingers crossed that fixes it.
Is there a quicker way in AU to change multiple at the same time or must i do them individually?

Look at the 'Batch process' in Audition

Please report back with your findings.
what did you apply? i would think that would be the problem more than whatever this NPC ACP is talking about. As far as I know if the timeline is working there should be no reason the export should be different than the timeline even if the audio bit rate is different.
I've only seen this behavior from Premiere when either using pitch shifter or automatic noise reduction... in short, Premiere can't accurately export some effects so it cranks out a messed up render instead of canceling itself, failing, or god forbid, just working as it's intended to.
