No, I mean stopping it so that it can never be resumed.

If GStreamer only supports those two actions, I wonder whether we
should have an abstraction layer above it.  But that could be in a
separate patch.

Well, I hope it will be.  Right now, even playing an audio in Emacs is
very restrictive: it locks up the main thread until the audio finishes
playing.  That's not appropriate for a modern platform, so I wish we
could have a better UI and UX.
