Yes, Xonar DS will work via DTS Connect.

I'd get the Xonar DS or the one in the link below:

Many of the cards that look they don't have an optical port, do have one. It's a toslink 3.5mm type. Socket looks any other 3.5mm analogue socket, but will accept mini toslink cable, or an adaptor. Xonar's come with an adaptor, not sure if the X-Fi Xtreme Gamer does.

yeah the creative cards tend to call them "flexi jacks".
