.attachSound crazyness

okay, so i have a sound linked from my library like so:


_root.loopSound = new Sound("_root");
_root.loopSound.attachSound("loopSound");
_root.loopSound.setVolume(0);
_root.loopSound.start(0,9999)
;

then, i have a movie clip that has this on it:


onClipEvent(enterFrame) {
	CurrentVolume = _root.loopSound.getVolume();
	if (CurrentVolume > 10) {
		_root.loopSound.setVolume(CurrentVolume - 1);
	}
}

On top of this i have streaming audio on the timeline that i want to play over this loop, the only problem is that the onClipEvent handler is also effecting the streaming audio, i thought with attach sound i was creating an indepent sound element, i guess I was wrong, or messing up on something small, does anyone know why this effects the streaming audio as well as my loopSound???
