Here is my code:

mcNext.buttonMode = true;

var mySound:Sound = new Sound();
var myChannel:SoundChannel = new SoundChannel();
mySound.load(new URLRequest(“audio1.mp3″));
myChannel = mySound.play();
mcNext.addEventListener(MouseEvent.CLICK, mcCLICK);
function mcCLICK(event:MouseEvent):void{
myChannel.stop();
var mySound2:Sound = new Sound();
var myChannel2:SoundChannel = new SoundChannel();
mySound2.load(new URLRequest(“audio4.mp3″));
myChannel2 = mySound2.play();
}
mcBack.addEventListener(MouseEvent.CLICK, mcClick2);
function mcClick2(event:MouseEvent):void{
myChannel2.stop();
var mySound1:Sound = new Sound();
mySound1.load(new URLRequest(“audio4.mp3″));
mySound1.play();
}

I got this error 1120:Access of Undefined property myChannel2 in myChannel2.stop();

What should i do? Please help.
Thanks in advance!

In the first SoundTransform code sample, you have:
var someTransform:SoundTransfrom = new SoundTransform(0.5); // the 0.5 value here tells it to set volume to half the maximum value

I think you mean someTransform:SoundTransform instead of var someTransform:SoundTransfrom…

Otherwise GREAT, clear overview. Thanks!
