Going through each state on the way back down to GST_STATE_NULL can cause deadlocks, for example: gst-launch-1.0 audiotestsrc ! valve drop=true ! autoaudiosink ctrl + C Hangs forever when going to PAUSED, because the "final" state is ASYNC, and the sink blocks waiting for a preroll buffer. Going straight to NULL addresses this issue, and also helps making teardown faster when piping sparse streams to a sync sink.
