title: Background audio doesn't resume after a call
body: <p>My background audio works fine almost all the time. Screen locked, or mute switch on. But when the user has the application in the background, and it receives a call, even if the user doesn't answer the call, the background audio does not resumes after the interruption ends. </p>
  
  <p>The Music app properly resumes background audio if it was interrupted. </p>
  
  <p>Am I missing some property or do I need to have a callback or set a background task to continue background audio execution after an interruption? Or this is something that we can't do?</p>
