title: Playing notification audio files outside of notifications in CN1
body: <p>I'm looking for a way to play the audio files which are used for <code>LocalNotificaiton</code>s (notification_sound_xyz.mp3) when clicking a button for example. </p>
  
  <p>I want to provide to the user the possibility to set the notification's sound as he prefer by previewing the sounds. I know that the notification audio files are moved to different locations depending on the OS. Therefore I'm wondering whether we can access those by CN.openFileInputStream or sth alike. Or do I have to write native code? </p>
  
  <p>Regardless of the approach to access these files, as a result I want to put the references to those files in a <code>MediaManager.createMedia</code>call from CN1 in order to play the previews.</p>
