I currently have:
Windows Pro 1809 17763.292
I have just updated my Realtek HD audio manager and drivers to: 220.127.116.1119 with windows catalog
Installing this latest driver allowed the Realtek HD manager HUI to start working again and appear in the taskbar as it did previously.
When I open the Realtek HD manager, the section where you used to be able to select whether the output is 2/4/5.1/7.1 channel, is no longer there?
I then attempted to go to the sound device properties to see whether I could see the 5.1 option and test it.
When I test the above DTS or Dolby, the 5.1 Audio is heard through each speaker.
However, there is no option to select the 5.1 option at a given frequency.
Also cannot select the configuration above.
And for some reason all my games do not allow the 5.1 to play, all is working as normal 2 channel(2.1) audio.
How do I return to getting my 5.1 surround system to play via the optical cable output???
