switch between 2 5.1 inputs

[s1rwilliam]

On my computer i have an xfi soundcard and i plug in my 5.1 speakers (3 connections) into that card. When i want to use my 5.1 headset i have to unplug the speakers and plug in the headset. Is there a spliter or something that i could plug both 5.1 inputs to and have that plug into the card and pick which one to use with a switch?
