sorry if i didnt make it clear
what i meant was, i have a digital audio cable from a device, i want to connect that device to my sound card, and then connect my sound card to my speakers
so that my sound card is taking two sources, one from my computer, and one from my external device, combine two sources and output to my speakers

Um, I think most sound cards will do it. Unless I misunderstand, all you really want is for the sound card to take the spdif input signal and mix it with the computer's own sound and output it back out to speakers, no? That's pretty basic functionality that I would think any soundcard with a digital input would be able to handle. I'm assuming here that the signal coming in is standard PCM audio.
