Flex Mobile - Sound Effect not Playing on List snapping (code sample provided)

Question

Hello All,
I'm trying to figure out how to play a Sound Effect on the trigger of the "changing" event on a List.
So basically I have:
<s:List id="theList" width="100%"
            itemRenderer="MyIconItemRenderer" verticalScrollPolicy="off"
            pageScrollingEnabled="true" scrollSnappingMode="center"
            caretChange="playSound(event)"> ... </List>
So the list above snaps to the item to be centered, though I would like on every snap, for it to make a click sound. I've added the method for playing the sound as:
private var tickChange:Sound;
private var soundEffectURLRequest:URLRequest = new URLRequest('/assets/sound/click.mp3');
protected function playSound(event:IndexChangeEvent):void  {      
     tickChange = new Sound(soundEffectURLRequest);
     tickChange.play();
The Sound effect plays, though it's not playing at every Snap interval, so if I scroll fast among them, it's not playing, only on the last selection.

I can´t believe it.. While writing the previous post, I thought on a really simple solution and compiled it to give it a try. It works perfectly!
As simple as setting the "cacheAsBitmap" property to "true" on the Spark lists of the views!!
