title: How to play the SMS alert sound in Windows Phone 8
body: <p>I'd like my app to play an alert sound and vibrate the phone when a certain page is loaded.  Specifically, I want to play the SMS alert sound effect that the user has picked from the settings.  I already have the vibration done, but I'm not sure how to get the SMS alert sound to play.</p>
  
  <p>Does anyone know how I would go about doing this?</p>
