How do i say "if a sound is already playing

hey guys, can someone tell me how to say

on (release) {
if myLoop is playing;
dont play myLoop;
and if its not playing ;
then play myLoop;
}

ok, so heres what ive figured out so far, in my timeline ive got :

myLoop = new Sound(this);
myLoop.loadSound("piano.mp3");
myLoop.start(0,999);

if (_root.emptyMC == "animationwork.swf") {
	 myLoop.stop;
}

could someone please help me figure out how to say that if any other mc is loaded into “emptyMC” then Dont Stop myLoop.

dudes, i been up all night trying to figure this out. i know it cant be hard, but im not a actionscript guy yet…im learning but i need some help. someone please???

well, after 2 and a half days straight, i finally figured it out on my own. this conversation with myself has been wonderous. trip trap trout, this tale is told out.

Yay? :h:
