Windows 10: Can't configure Realtek Digital Output

I have a Realtek onboard audio device connected via optical to my Yamaha receiver. The receiver's built-in 5 channel test works fine.
I just noticed that if I do a 5.1 channel test on my computer, I am getting no sound from my surround speakers. Left and right surround come from the front left and right.
Looking at the Sound control panel, I am unable to configure the Realtek device as the option is greyed out. Any help on this?

Update KB4038788 and Realtek digital output

After installing the KB4038788 update, I found that I had no audio output from my Realtek digital output, which is routed via optical cable to amplifier. I noticed that Device Manager says "Device not migrated". I updated the Realtek driver, but this has
made no difference.

Also since installing the update, Cakwalk Sonar Platinum crashes on launch.

 

cant get 5.1 on realtek digital output?

 

5.1 surround sound issue in Windows 10

Hi,

Thank you for your response.

I suggest you to follow the steps below and check if it helps.

If you’re connecting an optical cable the settings would be changed so try the following steps

Two options:

1. Use the optical S/PDIF output of your motherboard.

2. Use the HDMI output of your GPU. (This is what I'd recommend if you're using a HDMI display).

I suggest you to follow the steps below and check if it helps.

• 
  Go to control panel.
  
• 
  Select sound.
  
• 
  Click on playback devices.
  

For option 1- connect the cable and set the 'Realtek digital output' as default device.

• 
  Then right click on it.
  
• 
  Go to properties.
  
• 
  At the rightmost tab select DTS or Dolby Digital or 5.1.
  

For option 2-connect the HDMI cable through the receiver and set the 'Nvidia HDMI Output' as your default device. Then click 'Configure' and select 5.1 and check if it helps.

If the issue persist then, I suggest you to connect the speakers directly and check in the realtek audio manager if he gets the 5.1 option or not using the SPDIF\output.
