3.5mm - Toslink optical adaptor/cable

On my Pc I have the standard 6 headphone style outputs/inputs for the audio. What i'm looking for is something that'll let me link up those outputs (4 x 3.5mm jacks carrying the 5.1 surround) to my reciever which has both optical and coaxial inputs (Preferably Optical)

Is it possible? Please ask if I haven't explained well enough.

^^ Co-signed. Spdif output on motherboards has only recently been implemented, and you will likely need a soundcard. Assuming you want cheap, the Xonar DX would be the best solution.

There *might* be an adaptor out there that takes a 5.1 analog connection and converts to a spdif output, but that would likely cost at least as much as a soundcard. Doesn't hurt to take a look though.

If your receiver has a discrete analog 5.1 channel input you can connect to that using the analog outputs that you already have.

Other posible solutions are something like these:

and depends on your mobo connection this might work too:
