So I picked up the game yesterday and began playing on my 7.1 home theater, but noticed that the voices and surround sound was really low. So I turned the volume up on the individual speakers and discovered that yes, the game is sending the Dolby Digital signal through my receiver, the mix is only coming through in stereo. The surround speakers and the center channel are empty. I tested some other games to make sure my system wasn't broken or I had a bad speaker/speaker wire, but everything works except Dishonored.

Anyone else experienced this or figured out a potential fix (if there is one?)

Same issue here...

Driving me crazy!
