418 *          buffers in the queue, the playing of audio data stops. The player remains in the
419 *          SL_PLAYSTATE_PLAYING state."
420 *        - section 9.2.31 SL_PLAYEVENT states "SL_PLAYEVENT_HEADATEND Playback head is at the end
421 *          of the current content and the player has paused."
