Mute/unmute tracks according to changes in OP_PLAY_AUDIO for
  the current usage.
In audio policy: always assign AUDIO_STREAM_ENFORCED_AUDIBLE
  to sonification tracks with AUDIBILITY_ENFORCED flag.
Do not mute tracks from root / audio server.
Do not mute UI sounds on AUDIO_STREAM_ENFORCED_AUDIBLE
  stream type.
