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.
I have the same issue. After upgrading to windows 10 pro x64 (from windows 8.1 pro x64) I have not 5.1 surround on my Samsung htd 5550.

I use optical connection too. In fact when I go to control panelhardware and soundsound my Realtek digital output(optical) seems to work, but I can hear only 2 out of 6 six speakers working. The configure button is also greyed out so I cannot select 5.1 speakers. Moreover I can only see two tabs in the Realtek hd manager (digital input, digital output), the speaker tabis gone and there is no way to choose 5.1 sound like I used too. I have already tried removing Realtek drivers, installing the latest 2.79 to no avail. I have gigabyte eg41mf-ush2 motherboard.
