Toslink connection not recognized

Gigabyte Z68X-UD3H-B3 board, Win 8x64, UEFI bios. Tried to run good toslink cable from mobo optical out port to three good Dacs and not one has been recognized by Windows and Realtek. By not recognized, I mean literally the dac doesn't show in Sound. USB audio works fine and it will show under Sound, giving the Dac name. The Toslink cable end shows lighted red, I assume which means the signal is present. With Toslink audio off my TV, the same Dacs are recognized. What am I missing? Thanks,

What is your default output format? 48Khz? 96Khz? 192Khz? 16-bit? 24-bit? Is it an optical in/out, and is set to in? What kind of onboard sound is it, realtek?
 
While you were writing, I was editing to make it as clear as I can: I can't set something that's not recognized by the OS.
 
Last I recall, an optical out doesn't work quite like that. It wouldn't show in sound. It would show that it is connected in the realtek control panel, but not what it is connected to. All though, it has been a while since I used an optical connector from my PC.
 
Fair enough, but go back to my op. It wasn't in Reaktek cp: "You are seeing a blank page because there are no audio devices plugged in..."
 
How long and old is the toslink cable? Just because you can see the red light doesn't mean it's outputting a signal powerful enough for the receiving end to pick it up. Try a different cable. Earlier today I swapped out my home theater gear to a new rack and I had issues with my receiver not picking up the toslink out on my 360. I could see the red light but no audio... swapped the cable to a shorter one (it was running through a splitter so that degrades the strength of the optical output) and it clicked back on.
 
In the op, I wrote "good Toslink cable" because I knew from testing that it was good. How? Because I had used it on from TV to Dac for several weeks until I replaced it with a better one last month. One is a Monoprice "premium," purchase three months ago and the other Silflex was bought last month. Both are two meters, which is well within a typically workable length.

You're asking fair questions, but the answer doesn't seem to lie there. Like I said in my post, I've tried this three times with three different dacs over the course of the past couple of months, each time getting the same result. But I return to the TV set and everything is recognized. Can't figure it.

Do the analog out/inputs show up in the realtek CP? For that matter, do they work?

Nothing shows there now because I haven't been using speakers off the audio out ports for a few months. Still nothing shows there when I plug in the Toslink. I see that the optical out graphic is there, but if Realtek cp says no audio devices are present, it's hard to set anything.
 
I was asking, mostly, if the sound chip even works. I have a board right here that I'm working with that SAYS everything works, but there is no sound. Even though it detects things being plugged in, and the optical lights up fine. Fresh format too. No sound at all, regardless of drivers or settings.
 
Well, that's what I've been wondering - or worrying about. The only explanation that seems plausible so far. I've never had reason to use it before this, so it's not one of those things I would have checked early on with the mobo. If I really need one, there are boards (I came back to it again tonight because I wanted to burnin a new dac that doesn't have a USB input).
 
In sound, under the playback devices tab, right click and make sure "Show Disabled Devices" and "Show Disconnected Devices" are both checked.
 
I'll give that a try, but it's hard to believe it will go anywhere because show disconnected has always been checked and the Toslink connection hasn't ever been recognized, so why would it show as disconnected. I'm coming to think a more likely explanation is that the mobo's optical out isn't generating enough steam to power a dac. That's advice someone else received who had an analogous problem (using google as a sample, it seems a fair number of people have some kind of Toslink not recognized problem).
