How to stop the song from playing in Action Script 3 - actionscript-3

Question

I am trying to stop the song from playing when user clicks on a button, this is my code :
var mySound:MainSound = new MainSound();
var cmyChannel :SoundChannel;
animation_play.addEventListener(MouseEvent.CLICK, playSound);
function playSound(event:Event) {
mySound.play();
}
animation_stop.addEventListener(MouseEvent.CLICK, stopSound);
function stopSound(event:Event) {
mySound.stop();
}
animation_play.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame_3);
function fl_ClickToGoToAndPlayFromFrame_3(event:MouseEvent):void
{
gotoAndPlay(2);
}
when i click on the animation_play object it works perfectly fine, it does as how it should be by playing the sound and starting the animation from the specified frame. however if i click on animation_stop object i get an error
TypeError: Error #1006: stop is not a function.
Anyone know how to go about fixing this ?

Answer 1

You need to set the mySound.play() to the cmyChannel object. Then call stop on cmyChannel. Here is the code:
var mySound:MainSound = new MainSound();
var cmyChannel :SoundChannel;
animation_play.addEventListener(MouseEvent.CLICK, playSound);
function playSound(event:Event) {
cmyChannel = mySound.play();
}
animation_stop.addEventListener(MouseEvent.CLICK, stopSound);
function stopSound(event:Event) {
cmyChannel.stop();
}
animation_play.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame_3);
function fl_ClickToGoToAndPlayFromFrame_3(event:MouseEvent):void
{
gotoAndPlay(2);
}

To stop your sound, you have to use a SoundChannel object like this, for example :
function playSound(event:Event): void
{
cmyChannel = mySound.play();
}
and
function stopSound(event:Event): void
{
cmyChannel.stop();
}
Hope that can help.
