Audio Dropping Out In FCPX On Timeline & Export

I just got a new MacBook Pro and I've been having an issue where the audio (interview dialog + music) will just start dropping out on playback...and now it also happens in exported files. This is obviously NOT GOOD...any idea what is going on?

P.S. - This was not happening on my trashcan Mac Pro with the same project on the same RAID.

Thanks for any help!

1- Specs of new MBP?
2- Specs of media you're using?
3- Specs of drive it's on when working on MBP?

Sounds like the MBP is struggling to playback and is dropping audio in order to keep visuals playing smoothly.
