title: AUDIO_OUTPUT_FLAG_FAST denied by server warning in Android O
body: <p>Currently, I am working with <code>Android O</code> in one of our application, I'm receiving the notification but there is no beeper sound associated with it. I have set the sound to the notification channel but no results. I'm receiving a warning <code>AUDIO_OUTPUT_FLAG_FAST</code> denied by the server. Apart, from this no errors. Can someone please evaluate this?</p>
