Right on man I got the same set up expect my pc speakers are 7.1 so I have an input on my mother board for each speaker. I will need to get one of those connectors that converts the red and white audio cables to a standard audio jack and then put that jack in my computer audio in-port and bam 7.1 ( or somthing like that ) audio . Do you think this will work.
It works for me. I' m only doing 2.1 though. I don' t know if you can do 7.1 this way, probably. The following link shows you how and has a picture of what the adapter might look like.

So if that' s the case as it is with me. This is how your audio connections will look like the way I did it.
PC audio as it is now, with speakers directly into your soundcard or motherboard (if you don' t use a soundcard).
All other audio->switch box->red+white adapter->Line/IN
