Realtek optical out does not work in vista?

[jeanius1]

Built a brand new computer, using an ASRock x58 Extreme mobo, and using the onboard Realtek optical out. However, I get no sound through my speakers. In Vista sound playback devices, it shows that Realtek Digital Output gets a signal, but the Speakers are shown to be disconnected. The cable is fine, I've used this speaker set in my previous build with another sound card, but it won't work with onboard sound. In the Realtek sound manager, it doesn't show an optical port to be available, only a digital coax and the analog. I've enabled HD audio in BIOS, no change. Updated to latest drivers, no change. Anyone else have this problem?

I have the same exact issue with the ASRock x58 Extreme... The optical out doesn't show up in the list of connections in Realtek HD Audio manager
