In gst_pulsesink_change_state pa_shared_resource_mutex is taken before
pa_threaded_mainloop_new (obviously) and pa_threaded_mainloop_start, but I'm
not seeing any other thread in the GStreamer pulsesink code at the time of
deadlock, so I doubt that's the problem. There is this thread, though:

Thread 12 (Thread 0x7fffde486700 (LWP 24749)):
