I need help i can see mouths moving but the voice overs the audio isnt playing???

Have you downloaded the German language pack?

no im playing it in english when

It is probably related to this issue:

Currently the game has issues with various sound cards and speaker configurations as follows:
2.1
4.1
5.1
6.1
7.1

WORKAROUND: at present the workaround is to set speaker configuration to Stereo (2.0) or Quadraphonic (4.0) until the game is fixed.
