No Sound at all

Hi Guys, i got a little/big problem: i bought kcd few days ago, my pc should also easily be able to run game.
But when i start the game, i have no sound at all. Neither in the main menu or ingame.
Also the launch trailer wont start, only got blackscreen, but when pressing “esc” the icon to skip the video appears.
My sound drivers seem to be up date.

Would be very nice if someone got an idea to fix that. I have already read of people with the same problem, but no working solution for me

Hi, if you have a Nvidia GPU Card please try reinstall the Driver with this Option.
