A git bisect points at the following commit:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/commit/?id=e9d1819fe390e6c6d2d664387922e28003da470e

It looks like unref'ing the volume element in remove_sinks is the cause of the
behaviour I am seeing. This is because subsequent calls to gen_audio_element
(e.g. for the next media file) don't re-create the volume element.
gen_audio_element checks the cache for a "abin" (and returns it) and never gets
as far as creating the volume element again.
