8rda+ SPDIF and TV card won't work

I have the 8rda+ v2.1 with spdif daughter card. I also have the Yamaha
TSS-10 5.1 speakers. I was able to get the optical digital to work
(after changing board from rev 2.0 to 2.1).

But now I can't get my Sigma TV card to give me any sound out.

Would an Audigy 2 give me this option.


Thanks
