I put this in this thread because it has to do with my xbox 360 sharing my pc speakers. I have my pc hooked up to my monitor(gateway fhd 2400), and I also have my xbox 360 hooked up to my monitor with the red blue and green componet cables. I am not sure how I get get sound from the pc speakers? I knw that the 360 has an optical input on the cable, but I have no where to plug it in. My monitor does not have the red and white audio jacks on it. I do have a spare hdmi port on the back of the monitor not being used, but I have the original 360 without the hdmi hookup. Need help. Suggetions most appreciated.
