How to make a volume slider that uses channels - actionscript-3

Question

I am trying to make a volume slider that uses channels.
I am not sure how to do this.
Here is my code:
import flash.media.SoundChannel;
import flash.net.URLRequest;
import flash.media.Sound;
// Enter Frame Event
var sliderValue:uint = mySlider.sliderKnob.x;
addEventListener(Event.ENTER_FRAME, frame);
function frame(event):void {
sliderValue = mySlider.sliderKnob.x ;
status_txt.text = "Volume: "+sliderValue;
var snd:Sound = new Sound();
var channel:SoundChannel = new SoundChannel();
var volumeLevel = channel.soundTransform;
var req:URLRequest = new URLRequest("Background.mp3")
snd.load(req);
channel = snd.play();
var newLevel:Number = mySlider.sliderKnob.x / 100;
volumeLevel.volume = newLevel;
channel.soundTransform = volumeLevel;
}

Answer 1

You are instantiating and loading the sound on every single frame. And you need to make a new SoundTransform instance! I take it that the slider itself is working!
var snd:Sound = new Sound();
var channel:SoundChannel = new SoundChannel();
var volumeLevel:SoundTransform = new SoundTransform();
snd.load(new URLRequest("Background.mp3"));
channel = snd.play();
addEventListener(Event.ENTER_FRAME, frame);
function frame(event):void {
sliderValue = mySlider.sliderKnob.x ;
status_txt.text = "Volume: "+sliderValue;
var newLevel:Number = sliderValue / 100;
volumeLevel.volume = newLevel;
channel.soundTransform = volumeLevel;
}
