I looked at the code in the playlist initialisation that creates the aout.

I then tried doing the same thing in the libvlc media player creation code
(right after the input resource is created, just like is done in the
playlist).

The effect of this was that indeed an audio output is created and the calls
to get/set the volume no longer fail (i.e. they no longer return -1).

But...

Setting the volume before playing media still appears to have no effect,
and getting the volume now returns zero rather than -1. Only after some
time has passed after the media has started playing does an actual correct
non-zero volume get returned.
