Problem controling 2 sounds in Flash

programming flash
1

Hi,

I have some strange problem while using more than one sound that I want control.


var myMusic:Sound = new Sound();
myMusic.attachSound("music1");
myMusic.start(0, 999);
myMusic.setVolume(50);
 
var speach:Sound = new Sound();
speach.attachSound("speach1");
speach.start(0, 999);
speach.setVolume(50);
 
bttn.onRelease = function(){
 myMusic.setVolume(5);
}

When I try to reduce sound volume of 1 sound, volume of all sounds is beeing reduced?!
What am I doing wrong?

The same situation is when I use tween comands like: this.myMusic.volumeTo(5, 1, “linear”);
