Controlling the sound volume of my swf

Question

I am trying to reduce the sound volume of my swf in general. I implemented the code below, but I get this error message: Line 30 1151: A conflict exists with definition in namespace internal.
Thanks for your help

Here is my code:
package
   import flash.display.MovieClip;
    import flash.utils.Timer;
    import flash.events.TimerEvent;
    import flash.events.MouseEvent;
    import flash.media.Sound;
   import flash.events.Event;
    import flash.media.SoundChannel;
    import flash.media.SoundMixer;
    import flash.media.SoundTransform;
    public class BugGoopFSGame extends MovieClip
       public var mybackground:BackGround;
//        public var LetterArray:LetterArray = new LetterArray(stage);
        public var lettera:A;
        public var cinders:Cinders;
        public var gameTimer:Timer;
        public var spidy:Spidy;
        public var myplaybtn:Play;
        public var timerback:TimerBack;
        public var timermiddle:TimerMiddle;
        public var timerfront:TimerFront;
        public var settings_btn:Settings_btn;
        public var sound1:Sound1;
        public var channel:SoundChannel = (new Sound1()).play(0, int.MAX_VALUE);
        public var channel:SoundTransform = (new Sound1()).volume(0.5,1.0); //This is where the problem is - Line 30 1151: A conflict exists with definition in namespace internal.
        public function BugGoopFSGame()
            sound1 =  new Sound1();
        //rest is not relevant to this

Try this version that I put together. I attached the sound playing to the onClick function at the bottom. This may not be the correct place, you can move the code to any function that you like. The sound will not play from the variable declaration section of the class, it really needs to be in a function.

                              // this line tells the sound to play, it can also
                              // be "sound1.play(0,int.MAX_VALUE);" if you don't need
                              // the volume
                              channel1 = sound1.play(0, int.MAX_VALUE);
                              // set a value for the volume to be used
                           channel2.volume = .5;
                              // connect the volume to the sound channel
                  channel1.soundTransform = channel2;
