How can i set specific sound effects to a specific vol ?

[luke]

// 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 to set them all to my specific volume.

I was thinking something like....

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. 
 

I am also using flashDevelop to write most of my as3 and i would like to change the volume here. Thanks
