I just noticed something though.
When I quit zdoom, I have a grey file showing up with some error messages.
My great wife did a screenshot! 
Found it. In zdoom.ini
we have to change vid_forcesurface=false to vid_forcesurface=true

Hang on. New game. Crash. Don’t tell me it’s the same thing re disabling EFX in OpenAl?
Could be but I uninstalled it since zdoom works now.
