OK, tracking this down a bit further.
FWIW your test case works fine if you connect the media prior to
creating the path.
This comment seems to specifically mention this case:
I'm guessing that this work around either doesn't work at all, or no
longer works with current gstreamer.
This "reset" approach causes two streams to be created in PA. The first
one dies off straight away (e.g. after the eventloops runs post
constructor) and the second one should normally pick up where the first
left off but for some reason it doesn't..... I'm guessing it remains
corked in some capacity - e.g. the bugfix doesn't complete.
It would be nice if we didn't have two streams at all and that this use
case/scenario is handled more gracefully overall.
I'll try and find a fix (tho' I am by no means a gstreamer coder - bit
of a noob there, but I'll try my best seeing as there is not exactly a
queue of people willing to work on the phonon-gstreamer backend right
