停止AS3中的聲音

Question

我正在爲相冊製作一些互動廣告。它有4個可拖動的歌曲標題，當放在目標上時，開始播放歌曲。試圖找出如何停止播放新歌時播放的歌曲。這裏是我的代碼：

package { 
     import flash.display.*; 
     import flash.events.*; 
     import flash.media.Sound; 
     import flash.media.SoundChannel; 
     import flash.net.URLRequest; 

    public class Deftones extends MovieClip{ 

     function Deftones() { 

      swerve1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS); 
      swerve1.addEventListener(MouseEvent.MOUSE_UP, dragEndS); 
      polt1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS); 
      polt1.addEventListener(MouseEvent.MOUSE_UP, dragEndS); 
      rd1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS); 
      rd1.addEventListener(MouseEvent.MOUSE_UP, dragEndS); 
      gauze1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS); 
      gauze1.addEventListener(MouseEvent.MOUSE_UP, dragEndS); 
      var sound1:Sound= new Sound(); 
      var sound2:Sound= new Sound(); 
      var sound3:Sound= new Sound(); 
      var sound4:Sound= new Sound(); 
      sound1.load(new URLRequest("music/Swerve_City.mp3")); 
      sound2.load(new URLRequest("music/Poltergeist.mp3")); 
      sound3.load(new URLRequest("music/Romantic_Dreams.mp3")); 
      sound4.load(new URLRequest("music/Gauze.mp3")); 
      var channel:SoundChannel= new SoundChannel(); 

      function dragStartS(e:MouseEvent){ 
       e.currentTarget.startDrag(); 
      } 
      function dragEndS(e:MouseEvent){ 
       e.currentTarget.stopDrag(); 
       if (swerve1.hitTestObject(speaker1)){ 
        channel.stop(); 
        sound1.play(0); 
       } 
       else if (polt1.hitTestObject(speaker1)){ 
        channel.stop(); 
        sound2.play(0); 
       } 
       else if (rd1.hitTestObject(speaker1)){ 
        channel.stop(); 
        sound3.play(0); 
       } 
       else if (gauze1.hitTestObject(speaker1)){ 
        channel.stop(); 
        sound4.play(0); 
       } 
      } 

     } 
    } 

任何幫助，我將不勝感激。
