>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: WP7
>    Affects Versions: 2.1.0
>         Environment: Nokia Lumia 800 with WP 7.5 (7.10.8773.98).

> When using this code
>           function play(){
>             cordovaMedia = new Media("app/www/test.mp3", onSuccess, onError, onStatus);
>             cordovaMedia.play();
> 		  }
> 		  
> I encounter the following problems:
> * 1st call to play() does not work (ie: I don't hear the sound). nor are the callback called.
> * following play work, but callback are called multiple times.
> * onError is called even when play sound is successful (ie: when I can hear the sound).
> * if onStatus callback is not provided, an error show up in the log.
> Expected behavior:
> * onError & onSuccess should be exclusive. One OR the other should be called. Not both.
> * onError & onSuccess should be called only once per call to .play()
