Hey all, Pretty newbie problem im having. I cant figure out how to enable voice chat in pc games I have left 4 dead 2, crysis 2, and a few other games that require communication. I mostly use steam as gaming client but i do have a few disc copies that dont use steam. Please any tips or info on how to enable voice chat would be awesome!! BTW I use a turtlebeach dpx21 headset connected through a optical cable if that helps
