title: Play audio file from server
body: <p>I followed the steps to create a sample app and it is doing perfect conversation with my custom agent created. </p>
  
  <p>Can we play our own music or MP3 hosted in my server by a voice message to Google Home? Or I need to play an audio from my Android app that is installed in Android device which is paired with Google Home by sending voice message to it?</p>
