this is my code:

audioturnon.addEventListener(MouseEvent.CLICK, fl_ClickToPlayStopSound_12);

var fl_SC_12:SoundChannel;

//This variable keeps track of whether you want to play or stop the sound
var fl_ToPlay_12:Boolean = true;

function fl_ClickToPlayStopSound_12(evt:MouseEvent):void
{
if(fl_ToPlay_12)
{
var s:Sound = new Sound(new URLRequest("animalcrossingaudioClass.wav"));
fl_SC_12 = s.play();
}
else
{
fl_SC_12.stop();
}
fl_ToPlay_12 = !fl_ToPlay_12;
