Ok.... that didn't work neither.....
I shorten the track so that it was 325kb, selected it in the movie tab, previewed it an no sound!! Ahhhhhhh!!!!
Is the file that you are trying to use music? If so, you may have to use an editor and loop a section of it to reduce the file size. That is what I do. I find a spot where the music repeats and that is where I cut the track. This way, when you select the file to loop, it sounds continuous.
Ok, I finally got it to work with Adobe Audition: This is what I did:
Adobe Audition Conversion to Au.Files
i. Select Sample Rate to 8000
ii. Select Channel rate to Mono
iii. Select Bit Depth to 32
iv. Push OK
This worked for me. I can use any MP3 song, wave file, etc. and it will convert it to play in its entirity
