To make the sound objects more manageble, you can embed it in a container that 'adds' functionality to a sound object. For example, you can simplify playing, status checks, looping etc. by adding functions for that to the sound's container.

Here's an example:

function loadSound(sound:String, vol:Number, loop:Boolean):Object {
    var d:Number = _root.getNextHighestDepth();
    var emptyMC:MovieClip = _root.createEmptyMovieClip("empty" + d, d);
 
// multifunctional container
    var SoundObj:Object = new Object();
    SoundObj.sound = new Sound(emptyMC);
    SoundObj.sound.attachSound(sound);
    SoundObj.sound.setVolume(vol);
    SoundObj.sound.onSoundComplete = function() {
        SoundObj.isPlaying = false;
    };
 
    SoundObj.isLoop = loop;
    SoundObj.isPlaying = false;
 
// only start playing when sound is not already playing
SoundObj.softStart = function(Play:Boolean) {
    if (Play) {
        if (!this.isPlaying) this.sound.start(0, this.isLoop ? 999 : 0);
    } else {
        if (this.isPlaying) this.sound.stop();
    }
 
    this.isPlaying = Play;
}
 
// restart playing no matter what
SoundObj.hardStart = function(Play:Boolean) {
    this.sound.stop();
    this.isPlaying = false;
    this.softStart(Play);
}
 
    return SoundObj;
} 

Ofcourse, you can add only so much until it becomes more logical to create a SoundClass instead and hide the details away in there.
