Its been a while since I last played a game on my xbox360 - but I cant get 5.1 Dolby Digital to work with skyrim?

Does skyrim support DD 5.1? I tried it with another game and there it worked...
While skyrim running my audio receiver only displays "stereo 3.1"??

Maybe its too late or I am just so overexcited to play skyrim that I oversee something?!?!?

I will try my 5.1 sound system in a few hours and will post my experience in this thread.

Back as promised and running Skyrim on full 5.1 dolby sound... Check your connections & speakers.

thanks mate! well thats weird - guitar hero is running without any probs on full 5.1, then I swith to skyrim....3.1 (stereo) without changing any of the settings.
anyway, thank you very much for your help!
