Ok I have xonar asus dgx sound card with sennheiser hd 558 headphones. In windows I disable all on board audio and configures for 24 bit 48k with 7.1 surround sound. Tested and all speakers do make noise but can't tell direction if eyes are closed. On xonar I have it on 8 channels, 48k, 32-64 ohms pro gaming , dolby and 7.1 selected and I moved the speakers out a little further. Eq is in default. My problem is I don't feel I noticed directional awareness. People still sneak up on me and I hear foot steps just can't tell where there coming from. The sound is better than my on board but can't tell position. Also bf4 set at home cinema and surround tried other ones but noticed no difference. What settings do you have and or can you help me thank you
