You can hook a s/pdif out to a s/pdif in, and then IF, IF, IF, the card with the s/pdif in has software to tell it to accept it's clock from s/pdif instead of its crystal you could tell it to sync to s/pdif. I doubt that a SB has this capability, but I'm and optimist also, so go look I suppose. Wish it was easier, but your trying to do something with two $19 cards that I had to buy $500 cards to accomplish. I don't want you to be *too* successful. ;-) If you are a home brew type, you might possibly be able to find a clock signal on one board, cut away that signal on the second card and hook a wire between the two. That way both cards would run at 44099 Hz, if they ran at all... ;-) (If they didn't, it's only $19 though, right?) Good luck, Mark
