Mobo Digita Audio (Coaxial) or Not?

Mobo: Biostar TZ77B Ver. 5.x:

I need help on figuring out whether that Orange Audio Output is a Digital Audio Output (Coaxial), because in my Mobo manual it says Center instead of a Digital Audio. So is this the same thing as a Digital Audio? Thanks.

What speakers do u have? Whats your set up?

Usually the green one is the one.

I want to use the coaxial for a 2.1 speaker plus a center speaker, but it seems my mobo doesnt have coaxial which is why I'm interested in that orange output. when i play audio or games on my pc the center speaker doesnt come on.
