Hi, I only have 1 set of logitech 5.1 640 speakers that I want to connect both an xbox and pc audio outputs to. Right now, my setup looks like this, and here's a closeup of the adapter I have. I noticed, however, that not all my speakers work with my current setup unless I connect the speakers directly to my motherboard (MSI Neo2 Plat with ALC850 8 channel sound). Is there a way, possibly with different connectors, to get all speakers to fire while being plugged into both my PC and xbox? It's a real pain to either lose speaker functionality, or keep switching the speakers between my PC and xbox. Thanks for your help.
