No sound ingame

I wanted to play this game again after a while, but now if I play the game it has no sound. I suspect it has to do with nvidia, because with my amd card it all worked fine. I’ve tried downloading older version of this game and tried the demo from the site, but nothing works The game also doesn’t show up in my volume mixer. The only thing that worked so far is the demo from the windows appstore, but that’s obviously the demo and not the full game.

Edit:
It looks like the sound on the steam version works, but only with speakers and not with my headphones. I have the
RAPOO H8030.
