Controlling sound

Hey guys, I got this project that i need to finish and the sound part is the last…help me get paid!:smirk:

Ok, I got a main movie with a background sound (as a movie clip) and an empty movie clip (‘contents’) to load external Fla’s. The main movie has links to three other movies A, B and C.

As i navigate between the various external fla’s the bg sound should keep looping. When Movie A loads, it has it’s own sound and it plays, when I navigate away from Movie A and load Movie B, the sound for Movie A still plays, how do I get to stop the sound of only the loaded movies and not the background sound?

Does that sound confusing? Below is some code I used on the buttons to load the external fla’s

on (release) {

    contents.stop(); // Doesn't stop the sound in 'contents'

_root.contents.loadMovie(“audio.swf”);
}
