Audio configuration worked fine in Win 7, but not in Win 10 1903

Hi!

I had a custom audio config that worked fine in Win 7, but I haven't gotten it to work in my current Win 10 Pro 1903 desktop system, and I'd greatly appreciate some help.

Here's the key part of the config that's not working: I take the HDMI output from my Fire TV Gen 2 and plug it into a sound device with two outputs: One is just an HDMI thru so the video signal can continue, and the second is an S/PDIF optical output. Here's a link to that product:
eSynic 1080P HDMI Audio Extractor HDMI to HDMI + Optical TOSLINK SPDIF + Analog RCA L/R Stereo Audio Video Splitter Converter

Then I connect the S/PDIF optical output to the input of a different sound box, the one shown here: LogiLink USB 2.0 7.1 Channel Sound Box

This USB sound box is connected to my desktop computer running Win 10. A brief description of my problem is that my computer apparently doesn't "hear" anything coming from the optical link.

Here's what's supposed to happen (and what did happen under Win 7): The sound from the Fire TV moves to the USB sound box, where it enters the computer. An application (specifically, the MEmu Android emulator running the RiffTrax android app) takes that sound and synchronizes it with a specified movie -AND- displays the input waveform in real time.

But now I see nothing on that waveform display, and naturally I don't hear anything either. Note, however, that when the USB box sees optical input, an LED blinks -- and it correctly blinks under Win 10 also.

Would anyone be willing to help me sort this out, please?

Thanks!

ETA: I forgot to add that in the Sound Settings/Control Panel, the S/PDIF device is marked "unavailable" under Win 10, but not under Win 7. This is probably very important!

Not to state the obvious, but that "custom config" is probably not compatible with Windows 10. BTW please clarify what you mean by "custom config" as that can mean anything. Is this a file? A custom driver hack for a soundcard? A Windows registry tweak?

Also have you checked for drivers specific to Windows 10 for that HDMI Audio Extractor gadget?

The problem appears to be with your "LogiLink USB Sound box". Have you installed the manufacturer's drivers?

Hi, and thanks for your reply. I apologize for my vagueness regarding the "config" I referred to in my OP. What I mean is how all the hardware and software is laid out, how they're connected, and what settings I use in those items which have settings. They're all the same under Win 10 1903 as they were in Win 7.

The extractor box is driverless, since it isn't connected directly to my computer. It sits between the Fire TV and the USB sound box, and Windows couldn't tell if it was present or not.

I really think this is a 1903 problem. Why? Unfortunately, I forgot to note in my OP that this "setup/config" also worked fine under the previous release of Windows 10 Pro. Sorry!

It would help if I could see if some other application could see the S/PDIF optical signal coming in to the OS. I've downloaded a couple of audio level meters, but they all produce error messages and/or fail to show anything.

Thanks again!

Hello, @rqt, and thanks for responding. I have indeed installed that driver.

As I said in my reply above, I forgot to add that everything worked fine under Win 10 Pro 1809.

" I forgot to add that in the Sound Settings/Control Panel, the S/PDIF device is marked "unavailable" under Win 10, but not under Win 7."

I think that as long as this remains the situation you are not going to get any application to see your optical input.

That may well be, but I'm more and more convinced that's where the problem is. Under Win 10 1809, it always showed as "available", even when nothing was connected and no applications were running.

I wonder what that "unavailable" really means in the end. Perhaps some registry value is missing or incorrect? I'm going to leave this open here while I go and ask Microsoft.

Thanks for sticking with me!
