I have a box with a AsRock z77 extreme4 motherboard. Just got a new headset, which is a Razer Tiamat 7.1. Both devices state they support 7.1 channel surround. There is however a mismatch between the 5 cables from my headset and the 5 audio ports on my motherboard.
Does this mean I cannot connect this headset to my box without getting new hardware? I tried connecting it with the 4 matching connections which results in bad sound. Since I don't know if this is a hardware problem or not, I'm not sure on how to fix this. The information out there on 7.1 surround support is somewhat contradictory at places :/
I'm running Kubuntu 13.04 x64 as OS.
