Hi everybody!

I’ve been trying to make some buttons to load and play (in stream) determined sounds, but Error compiler shows error 2007, and I really don’t understand why listener it’s getting a null value. Can anyone help me?:hang:

Here is the code:

```auto

import flash.media.Sound;
import flash.media.SoundLoaderContext;
import flash.net.URLRequest;
var s:Sound = new Sound();

var tocarSonido = function (req:String){
    //trace (req);
var context:SoundLoaderContext = new SoundLoaderContext(1000, true);
s.load(new URLRequest(req+".mp3"), context);
s.play();
}

a_btn.addEventListener(MouseEvent.CLICK, tocarSonido("a"));
b_btn.addEventListener(MouseEvent.CLICK, tocarSonido("b"));

```
