That's what I had been thinking all the time too. It's only when you draw my 
attention to config_help.txt and saw the "unix only" remark that I had the idea 
to scout configure.json for something that could limit the pulseaudio option to 
unix. Edit: I hadn't actually checked supprt for -[no-]gstreamer before; it 
turned out this option *does* exist on Mac, so I knew to search for a difference 
in the handling of pulseaudio and gstreamer.

There is another reason why this shouldn't make sense: config.unix should be true 
on Mac.

I can try valgrind, but finding something useful among the big load of output 
isn't going to be trivial.
It should be a lot more straightforward for you to check if you can reproduce 
the effect. Could this be a side-effect of some kind of interaction with other 
things in the configure.json file?

Yes, it would appear so.
I should check to see what happens when I introduce the line I removed in this 
option, to see if that has any effect.
