How can I set a specific sound effects to a specific volume?

Question

I have a variable set

var vol = 0.25;

this var changes on demand and works fine.

In my flash game I have some sound effects on movieclips that sound only when the movie clips are being played.

I would like to set all of my sound effects to the same volume in one as3 file.

Although I have my sounds playing in my timeline on as3, is there a way to get all of my sounds together on one as3 file in order to set them all to a specific volume.

I was thinking about something like this:

var isSoundOn = true;
if (isSoundOn == true) {

    // get all sounds that i would like to change volume on
    // if in game play and any of the sound effects are ready - play all these sounds with my specific volume setting.

}

my code looks a bit like this but doesn't work

In FlashDevelop... My main Class...

public class Platformer extends GameLoop
{
public var redMonster:RedMonsterFla;
public var SoundFxVol:Number;


public function Platformer( )
{



}

    // here i have functions that open a popUp
    // inside the popUp i can change variable "SoundFxVol" with my volume slider  


    // here i would like to set my volume to some of my movieClips with soundFx

public function set VolumeForSoundEffects(value:Number):void
{
    // set array of movieClipsThatContainSound


    var movieClipsThatContainSound:Array = new Array( redMonster );

    var st:SoundTransform = new SoundTransform(value);

    SoundFxVol = value;

    for each( var mc:MovieClip in movieClipsThatContainSound  ) mc.soundTransform = st;
}

public function get VolumeForSoundEffects():Number
{
    return SoundFxVol;
}

}

I flash I have a movieClip called RedMonster with a library linkage to as3 as RedMonsterFla; On redMonster MovieClip I have lots of labels, one of them is jump - this has a sound. There is no code on the redMonster timeline.

You can use your movie clips' soundTransform property to adjust volume of those sounds that are played within it. But, you cannot set a var and get all dependant SoundTransform objects to adjust themselves, so write a setter property function.

private var vol:Number=1.0;
public function set volume(value:Number):void {
    var st:SoundTransform=new SoundTransform(value);
    vol=value;
    for each (var mc:MovieClip in whateverArray) mc.soundTransform=st;
}
public function get volume():Number { return vol; }

whateverArray is supposed to be the array that holds all the movie clip instances that are dependant on setting volume here.
