I didn't see any sound hardware setup in the game menu. I have 6 speakers with 5.1 surround (7.1 virtual) and most games sound superb on them. The nades make almost no sound at all (can't even hear them go off for the most part) and the VO sounds like he's talking on a cheap AM radio in another room. Also getting a huge whine through one of the speakers even when I MUTE the game; it goes away only after I exit the game. I'm uber picky about sound so looking for some input from others about how it sounds to them. . Plus side this game is really SMOOTH when it comes to key bindings, mouse movement and video hardware..
