如果有两个按钮，button1，button2，当点击button1,时播放sound1

当点击button2的时候播放sound2

当点击，比较快的时候就回发现声音重复问题

var button1:Button;
var button2:Button;
var player:String = "";
var soundChannel:SoundChannel;

button1.addEventListener(MouseEvent.CLICK,clickHandler);
button2.addEventListener(MouseEvent.CLICK,clickHandler);
function clickHandler(e:MouseEvent):void

	trace(player);
	switch(e.currentTarget){
		case button1:
			music=sound1;

		case button2:
