Make sound play on click - Help please

The sound only plays when I hold the mouse button down. I need  it to play when I click it. But it has to stop the sound from  playing twice

import flash.media.SoundMixer;
this.addEventListener(MouseEvent.MOUSE_UP,f);
function f(e:Event):void{
SoundMixer.stopAll();
}


here is a link to my swf file
