Comment (by barracuda156):

 Replying to [comment:28 RJVB]:
 > Ah yes, I remember running into code that required those changes to
 build. Honestly, I wouldn't bother backporting, I'd first try a PulseAudio
 version from before that patch above.

 I have found something potentially interesting, though old:

 Does not work on either systems, though fails a bit differently.

 > Do you have a VLC2.x version that makes sound through CoreAudio on your
 legacy systems? If so I'd try to get the CoreAudio "driver" to build and
 work with VLC3.

 That is not trivial, unfortunately, since the code in libauhal depends on
 general VLC headers (like `vlc_es.h`) and just replacing with VLC2
 versions does not work. So now the question is whether it is easier to fix
 the current code and restore the older but working one (which would
 require modifying stuff beyond CoreAudio plugin).
