Tree Komponente und Sound?=??

[NDC]

Hallo weiss jemand mehr zum thema sound in zusammen nhang mit der tree komponente:
wie kann man eigentlich die selected node abspielen?
hier das script

var trDP_xml:XML = new XML("<node label='ARTIST'><node label='MUSIC.mp3' value='MUSIC.mp3' data='MUSIC.mp3'/><node >");
tree.dataProvider = trDP_xml;

var xmlListener:Object = new Object();
xmlListener.result = function(evt:Object) {
_global.rootProducts.tree.setIsOpen(tree.getTreeNo deAt(0), true);
};

xml_conn.addEventListener("result", xmlListener);

treeListener.change = function(evt:Object) {



if (_global.rootProducts.tree.getIsBranch(_global.roo tProducts.tree.selectedNode)) {
trace(_global.rootProducts.tree.getIsBranch(_globa l.rootProducts.tree.selectedNode));
if (_global.rootProducts.tree.getIsOpen(_global.rootP roducts.tree.selectedNode)) {

//trace(_global.rootProducts.tree.selectedNode);
_global.rootProducts.tree.setIsOpen(_global.rootPr oducts.tree.selectedNode, false);
//trace(_global.rootProducts.tree.selectedNode);
var Sound:Object=new Sound();
Sound.loadSound(tree.currentItem,1);
} else {

_global.rootProducts.tree.setIsOpen(_global.rootPr oducts.tree.selectedNode, true);
trace(_global.rootProducts.tree.selectedNode.curre ntItem);
var Sound:Object=new Sound();
Sound.loadSound(tree.currentItem,1);
}

} else {

var Sound:Object=new Sound();
Sound.loadSound(tree.currentItem,1);
var node = evt.target.selectedItem;

_global.nCurrentPid = Number(node.attributes.value);


if (_global.nCurrentPid) {
//trace(_global.rootProducts.tree.selectedNode);
_global.rootProducts.mcProduct._x = 353;
_global.rootProducts.mcProduct._y = 200;
_global.rootProducts.loadData();
_global.rootProducts.mcProduct.highlightMCButton(_ global.rootProducts.mcProduct.mcDescription.tDescr iption);

}
}
};
tree.addEventListener('change', treeListener);
