You should be able to find something at Radioshack that will do that for you. If nothing else you can convert the 1/8" to RCA and get like a switch box-type thing that will let you select what input you want. I have one for audio and video that I got from Circuit City for like 30 bucks, but you can probably find something cheaper cause the thing I have is meant for a tv. But you should be able to find something at Radioshack that will bring them together. You likely will not be able to input both sources at once though if you were planning on that.
