I am currently using a Platronics RIG 400 gaming headset, 3.5mm audio jack that is managed by Realtek HD Audio Manager, and it just sounds absolutely terrible. It does not split the left and right sounds to the corresponding headphones. It plays the left channel in BOTH headphones, and I cannot hear the right channel at all. This really makes a big problem when playing games like CS:GO because I can't tell where enemies are coming from because it just sounds the same from any direction.
