Hi. I've been having trouble getting 5.1 audio in this game. I have tried every single possible combination of settings in the audio settings yet none of them seem to work to get me 5.1 audio. I'm using Windows Vista 32 bit with Realtek HD integrated audio with the Windows default High Definition Audio Device driver. I have to use that driver because the official Realtek driver causes the sound to go quieter. However, I have not had any problems with doing so in the past and all of the other games I play have 5.1 audio just fine. Is there a fix for this?
