I'm in the process of trying to connect my pc to my hifi via the optical spdif on my mobo in order to avoid blowing my amp (which I already did twice). This mobo, when new, comes with a sound card that doesnt have optical spdif on it (which makes no odds because theres one on the mobo and by the time I received this board the soundcard disappeared). Point is, which driver to use? So I put in the realtek software and it just disappears. Nothing in the startup programs and almost no sign of it in the program file. The "official" driver for this board is from "Soundmax" which won't install because there's no deicated sound card. The existence of the optical spdif is mentioned in the user manual but nothing about how. Please advise. Thanks in advance.
