Sorry if there’s already another thread like this, I just didn’t see one. I have my music loop goin’ and yes, the sound file is a loop, but at the end of the song, it stops for like, 5 seconds, then starts again, how do I stop the 5 second thing???
mySound = new Sound(this);
mySound.attachSound("mp3Name");
mySound.start(0, 99);
Right click on your sound file in the library. Choose “Linkage” Check the box that says “Export for Actionscript” (or something along those lines). Change the name to whatever you want, and that is the name you use in the above AS in quotes.
THANK YOU!!! 
No problem:)
