Ok, so, I got the narrator sound to work.
In windows I can activate the Spatialsound for my speakers, and I did, but, that didn't work for my headphones. (I never had a problem with narrator voice with the pc speakers so I inactivated it again.)
My headphones for some reason are not registered in windows sound setup.
I use a program called Audioswitch. In that I just found that I can activate Spatialsound specifically for my headphones. I did and now I have narrator sound.
So, now I just need to get rid of the annoying data missmatch error, somehow.
