Mute and unmute button is actionscript 3.0

Question

Hi,
I am wondering how to make a mute and unmute button is actionscript 3.0.  I did it before in actionscript 2.0 but not in 3.0.
Here is my actionscript 2.0 code.
var sound = 1;
var slashMC = _root.attachMovie("slash","slash01",99);
slash01._visible = false;
slashMC._y = btn._y;
slashMC._x = btn._x;
var s:Sound = new Sound();
s.attachSound("Gravy");
s.start(1,999);
btn.onPress = function(){
if(sound==1){
  s.stop();
  slash01._visible = true;
  sound = 0;
else if(sound==0){
  sound = 1;
  slash01._visible = false;
  s.start(1,999);
Thanks

Try this:
    import flash.display.MovieClip;
    import flash.events.*;
    import flash.media.*;
    import flash.net.URLRequest;
        var isPlaying:Boolean = false;
        var snd:Sound = new Sound();
        var channel:SoundChannel = new SoundChannel();
        var pos:Number = 0;
        var soundVolume:Number = 1;
            snd.load(new URLRequest("something.mp3"));
            btn_Stop.addEventListener(MouseEvent.CLICK, stopMusic);
            btn_Stop.buttonMode = true;
            btn_Play.addEventListener(MouseEvent.CLICK, playMusic);
            btn_Play.buttonMode = true;
         function stopMusic(evt:Event):void
            channel.stop();
            pos = 0;
            isPlaying = false;
         function playMusic(evt:Event):void
            if(!isPlaying)
                channel = snd.play(pos);
                btn_Play.visible = false;
                btn_Pause.visible = true;
                isPlaying = true;
