Load external sound file with actionscript 2(and not 3!!!)?

Hello every body

first question is it really possible to load a external sound file (wav or mp3) with actionscript 2 ?

I hope you 'll be able to help me
I would like to load a external sound file (wav or mp3 ) i assume that the other format doesn't work

//implented actionscript 2 

class Main 
{
	
	public static function main(swfRoot:MovieClip):Void 
	{
		var v:Main = new Main(swfRoot);
	}
	
	public function Main(s:MovieClip) 
	{
		var k:Sound = new Sound(s.rcp);
		
		s.g.onPress= function ()
		{
			
			k.onLoad = function(b:Boolean)
			 {
				if (b)
			 {
			k.start(0, 4); s.z.text = "rien entendu " + b; k.start(0, 99);
			 } // fin de if
			else { s.z.text = "merde"; } //fin de else
			} // fin de k.onLoad 
			
			k.loadSound("da.wav",true);
		} // fin de s.g.onload
	} //fin de public function Main
	
}//fin de class main

<code>
// tuto.swf to be impleted

present object on the stage
instancied symbol named :rcp
instancied button named : g
instancied textfield named:z

environnement
the implented swf is in the same folder than "da.wav"
my problem is that the file is loaded but the sound doesn't work on click event
