[flexcoders] SoundTransform don't work

[mychemic Carlo Gulliani]

How can I change volume of sound in my app

I used next code
<?xml version="1.0" encoding="utf-8"?>

<Script>
<![CDATA[
    import flash.media.*;
    
    [Embed(source="sound/music.mp3")]
    [Bindable]
    public var sndCls:Class;
    public var snd:Sound = new sndCls() as Sound; 
    public var sndChannel:SoundChannel;

    private functioninitApp():void{
        sndChannel=snd.play();
    }
    
    public function changeVol():void{
       sndChannel.soundTransform.volume = 0;
    }
]]>
</Script>
<Button label="Mute" click="changeVol()"/>
</Application>


But this code don't work. Ask me, what's problem?

Thanks
