Help with sound if you please

1

how can I make this sound to start automatically. for some reason it waits till I touch the volume bar. THanks!

this is the code inside the volume slider:

onClipEvent (load) {
mySound = new Sound();
mySound.loadSound(“IgalLoop.mp3”, false);
}
onClipEvent (enterFrame) {

downloaded = mySound.getBytesLoaded();
total = mySound.getBytesTotal();
if (downloaded != total) {
	_root.dl = "downloading song...";
} else {
	complete = 1;
	_root.dl = "";
}
mySound.setVolume(_root.volume);

}

this is the code in the first frame of the volume slider:

this.ratio =0;
dragger._x=100
dragger.onPress = function() {
this.startDrag(true, 0, 0, line._width, 0);
this.onEnterFrame = function() {
ratio = Math.round(this._x*100/line._width);
_root.volume = ratio;
};
};
dragger.onRelease = dragger.onreleaseOutside=stopDrag;

thanks so much for your help!!!
