I have now tried to reinstall to no avail
I understand that the problem can be solved by setting sound to stereo output ... on console I assume there is an ingame option to do so? On the computer version you cannot set stereo anywhere inside the game. At least I have not found it.
I have a creative X-Fi soundcards and a surrond 5.1 system. can someone suggest which setting needs to be set to play with voices?

Okay, managed to get it working.
Seems like setting audio form 5.1 to 2/2.1 speaker Mode did the trick
