Rob, I have the same sound card!!Turtle Beach Montego II. Maybe this the cause? I will re-check for new drivers. The sound I am getting is very basic, "move out, aguh! some cannon fire if you are close to the tank etc etc. I just want to be clear on this issue. What I am talking about is sound heard across the battlefield at the same time. For example, in CC3 the sounds of battle can be heard across the field of battle Thanks for all who posted.
