I have ArmA 2: Combined Operations standalone (not the steam version) installed. The problem I have is that the game only transmits sound to my front speakers and not to my rear speakers. When I initially installed only the ArmA 2 and launched it I got sound from my front speakers and left rear speaker! But now that I've updated the whole package to the latest 1.62 version I only get sound from the front speakers. Can you tell me a fix for this? My specs: Intel i5 2.67Ghz 4GB RAM EVGA GTX 460 1024MB Windows 7 64 bit Creative X-fi XtremeMusic (latest driver from creative installed) DxDiag can be found from here: http://pastebin.com/33GGpNhi I run my settings stereo surround and most games work fine. EDIT: Fiddling with my sound card options I now have some sort of 4.1 setup working but I seems that I cannot get stereo surround which would give an even environment sound (the all around ambient sound for example in bootcamp) to all my speakers. I only hear some sound effects from my rear speakers that are located on my side or back. It could be that the game does not support better Environmental Audio but I highly doubt it. Any ideas?
