At last! Sound bar synchronisation problem fixed!

I've done it, the last major problem overcome! This one was a big relief, in with it being so close to the deadline.
The solution (dont ask why this solved it!):
I decided to initalise all the sound objects in the main screen file in their own layer on the first frame on the root timeline. Originally I had some initialised inside the stadium movie clip. My prediction is that the code for the sound objects was being overriden somewhere or was failing to be read when the main screen was returned to. Initialising them all on the root timeline on thier own layer ensured that they couldnt be obstructed or interfered with.
