The thing is, its either this.. Or I hook my Logtech X530 straight to my computer with the Green, Orange and Black cable.. and use the Line in on my integrated sound card to allow the Xbox to connect via RCA > 3.5mm
use the Logitech games console adapter that connects the red/white RCA straight to the speakers and makes them all work as stereo. Which will not get me the 5.1 from my xbox, I think the only way to get 5.1 through my X530 on an xbox360/PS3 is via this decoder!
