  of the ramp time preceding a notification sound. Do this only
  for notifications that play a sound.
Tests: verify that calls to Vibrator.vibrate() method are within the
  max delay that could be applied to a notification sound/vibration.

Test: play notification with vibration, verify vibration syncs with sound
