Forza horizon 3 Online no sound

[THB_NL]

Hi people,

So I'm struggling with my sound problem in the online mode of forza horizon 3 (PC).
every time I switch to Online, my sound's (car-engine, music, etc) stops immediately. The only thing I can hear is other people speaking, but no other sounds.

So I tried:

 

1 reinstalling it
2 reinstalling my drivers (clean installation) 
3 checked the settings in game (all on)
4 checked the Xbox app settings
5 checked the Microsoft settings
6 Checked nvidia settings
7 tried going into the festival site or barn finds ( I thought maybe the film-sequence would help)

So I tried a lot...

 

Please help people
Thanks in advance (playing a racing game without sound kinda sucks)

Did you check the audio output setting?

Yes, it stays the same.
