indeed, in gst_base_audio_sink_change_state() we take the object lock:
    ...
    case GST_STATE_CHANGE_PLAYING_TO_PAUSED:
      /* need to take the lock so we don't interfere with an
       * async play */
      GST_OBJECT_LOCK (sink);
      /* ringbuffer cannot start anymore */
      gst_ring_buffer_may_start (sink->ringbuffer, FALSE);
      gst_ring_buffer_pause (sink->ringbuffer);
      GST_OBJECT_UNLOCK (sink);
      break;
    ...
