To create new sound objects that you can individually control, use can use the following function:

function loadSound(sound:String, vol:Number):Object {
    // create sound container
    var d:Number = _root.getNextHighestDepth();
    var emptyMC:MovieClip = _root.createEmptyMovieClip("empty" + d, d);
    // create sound
    var sound:Sound = new Sound(emptyMC);
    sound.attachSound(sound);
    sound.setVolume(vol);
    return sound;
} 

Usage:

var gunshot:Sound = loadSound("gunshot", 100);
var squeeky:Sound = loadSound("squeeky", 60);
