New change: In windows 10, 64bit,I forced the dolby digital plus to run in compatibility mode as if it was windows 8.
Then, the Dolby Digital Theater 4 window appeared ok correctly on my screen,
however I adjusted settings in Dolby Digital Theater Window buttons but no any changes had happened to my sound.
Although I tried to change many settings, the sound was remaining always the same.
Then I reinstalled again the latest HD realtek sound driver.
This time, the window Dolby Digital Home Theater 4 could not run,
and an error message appeared on screen, same as before.
I had tried to download dolby digital plus from dolby website,
but there is not any link, they just have some links to known manufacturers' websites.
Those links go to the main page of each manufacturer, and dont show any clue about where the download link
of dolby digital plus is in the site.
My pc is Gigabyte but I couldnt find any download link for dolby digital plus that runs correctly.
How can I run Dolby digital plus in windows 10 64bit?
