Android 6.0.1 release 79
DO NOT MERGE. Fixed emergency alert TTS not playing on bluetooth speaker.

Added an extra param so TTS engine knows where to route the audio.
Also release the audio focus at the time after tone + TTS are played,
not just tone so TTS won't mix with other audio stream (e.g. music)
