title: Playing voicemail via MediaPlayer turns alarm volume silent
body: <p>I play an audio file from a URL using MediaPlayer. The file plays fine, however after playback (if the app hasnt't been explicitly killed), alarm ringtone is silent. What do I need to clear/reset on end of playback to make this not happen?</p>
  
  <p>Code for the file I am using to control the voicemail playback.
