5.1 Channel Surround Sound not working in Windows 10.

I recently upgraded to Windows 10 from Windows 7.

Upon doing so my 5.1 surround sound home theater system is no longer working.  It is a Samsung CT-5550 Home Theater System.

I am using an Optical cable from my Home Theater system into the back of the motherboard.

I have installed Realtek's Windows 10 driver, Gigabytes Windows 10 driver, the driver that came with my motherboard, that previous worked on Windows 7 and fiddled with all manner of settings between all of them and nothing.  It is not working.

When I set the output to 5.1 and run a test, it tells me Test Tone failure.

The highest output I can get is 2.1 channel @ 48hz.  I can get 2.1 @ 92khz but it's spotty.  The curious thing is, when I test the Encoded option for Dolby, it works.  I can hear it out of all speakers.

Please someone, anyone, fix this for me.

For reference, here is what I'm looking at.

This is my speaker system.

When I test the Encoded Format Dolby Digital, the test runs through all the speakers and I can hear the tones.

Dolby Digital Plus is listed as "On" but for some reason did not show in screenshot.

This is what I get once I set both Realtek control panel and default format to both 5.1 channel surround sound and run a test.

All is set as it should be, it's just not working.

My guess is MS since I have the same issue with completely different audio hardware.

OK, so it's definitely not my Motherboard Manu, then as people keep trying to put the blame on them.  It also isn't Realtek's fault because some people are reporting having Creative Lab issues and that's not Realtek.

So this is either Dolby's fault or Microsoft's fault.

Frankly, don't really care whom's fault it is, I just want it fixed.

My $250 Home Theater Surround Sound System should not be made useless just because I installed a new Operating System.

I'm actually curious about how and why it happens, can you go into detail?

I suppose I should ask about an ETA for the fix.

Howdy? I read that this bug has been an issue since March. Can we get an estimation on when this will be fixed? I wasted three days thinking it was on my end and actually did two clean installs but in actuality it was yours. It would have been nice to have been given a heads up. Just saying.

Correct me if I am wrong but I believe the one you are thinking of only affected non-optical 5.1 systems.  That was since patched with a specific update.

This bug is affecting all Optical connected systems.

That or it's re-surfaced but it was fixed.

You are right. I misread. Stupidity on my part. Anyways I specifically bought the motherboard I have because it had an optical output that I could connect to my surround sound system. Alien Isolation sounded so awesome on it. Very frustrating that I cannot choose DTS 5.1 now that I have Windows 10.

I know how you feel.  I too have been buying Mobo's specifically because they have Optical In's on them so that I can link it to my Home Theater system.

I used to watch Youtube and DVD's in 5.1 mode.

But they will fix it, no worries.  It might just take a bit.

If you have a Stereo headset you could download a program called Razer Surround.  It will allow you to take any stereo headset and make it play 7.1 channel surround sound and it ACTUALLY works.  It works very well, indeed.

It's not REAL surround sound though, it's all software based.

It's how I have been coping with my lack of 5.1 from my speakers.

I don't mean this as a solution or anything, just a way to cope until they fix the issue.
