Crashes when I change sound device

Today I accidentally changed my sound device in beamng and when I try to change it back the game crashes every time. Is there anyway I can fix this I have no sound.

 

There's no official way to fix this unfortunately, but try this:
Try clearing your cache, this is possible from the boot menu that appears when you launch the game.
Try reinstalling the game, this may reset your options.

I'm sure someone (maybe a moderator) will have a fix that I strongly recommend you to read below this.

 

ok thank you
