Hi! This is my first time posting on here. I bought a G1 sniper Z87 motherboard which it says has Dolby digital live on it. I run my PC through my TV using HDMI and i'm trying to get my games running 5.1 by connecting the PC to the home cinema system using spdif. I understand that Optical cables run 2.1 unless encoded by Dolby. I'm not getting any surround sound. The sound blaster control panel 5.1 test is just silent. Where am i going wrong? Or am i just being stupid?? Cheers!
