Hey guys! I am trying to connect my Gamecube to my PC soundcard or PC speakers so I can have all of my gaming on my LCD monitor (I'll be connecting my Xbox to my speakers using fiberoptic cable). The audio output from the Gamecube is a set of RCA (red/white) cables, and the aux. input/line in into both my soundcard (Hercules Fortissimo III) and my speakers (Logitech Z-680s) is a 3.5mm (1/8 inch) jack. I was wondering if a Y-cable with 2 RCA female ends and one 1/8'' headphone jack is what I'm looking for. Will this work and give me good audio quality? Thanks.
