Digital input on Audigy2 ZS

[WAK47]

Hi,
I recently bought an Audigy2 ZS Platinum card on eBay, however the drive with the digital inputs was not included. Are there any accessories available for my card that would give me digital inputs?
If not, is there any other way I can plug my Xbox 360 into my sound card and get surround sound?
Thanks for your help

This should work.

It doesn't list the Audigy2 ZS under the compatibility list, although I can't see why. Any thoughts?
