HeyyI'm looking for a simple or easy way to use 5.1 sound system on my headphones, Roccat Kave. Its got 4 output wires, stereo, mic, subwoofer and one more yellow one for back and front speakers. So i would need a 5.1 soundcard to plug it in externally cz im in uni with just a basic laptop. i asked this in the pc forums but nobody knows where or hw, so.. Help me out if u can?
