Greetings all.

I have a motherboard (Asus Z97-WS) that already has optical out on the rear panel. It also has a spdif/optical out header.
1) If I get a the spdif/optical out bracket, is it possible I can use both the rear panel optical out as well as the one on the bracket?
2) If yes, could they output different audio streams?
3) The same motherboard does not have coaxial out, except through use of the spdif/optical bracket. Even if the optical part of the bracket wouldn't work, would the coaxial?
