In my experiences it's as Clemens said, there always should be light, but ... perhaps your card does provide optical and coaxial SPDIF and you need to set some jumpers on the board?! Just a shot in the dark. My card, a professional sound card, does provide ADAT, this is optical and at the same time it does provide SPDIF coaxial, but I can set it, to use the optical ADAT IOs, to become optical SPDIF IOs ... IIRC ;), I don't need SPDIF. I remember that a blind user couldn't get SPDIF working for his Envy24 card, using alsamixer. Since I've got Envy24 cards installed as MIDInterfaces, I used the GUI for those cards and compared it with alsamixer. The blind user struggled hours and couldn't get SPDIF working, while it took just a few seconds, when I used the GUI mixer and compared it with the settings for alsamixer and then sent him what t do by email. IMO alsamixer sometimes is hard to understand ;). The blind user, that blind that he does use Braille, but not completely blind user, was able to notice a red light, but there anyway was no sound, so I guess, if there's no light, something might be fishy. But again, just a shot in the dark.
