Re: Uninstalled Dolby digital Plus - Lenovo y50-70

hi sahilnair,


I see now.

The Audio Driver you have is lower that's why you need a lower versioni of the Dolby because it should be in sync.


Try this Uninstall the Audio driver first from Device Manager, be sure to do it this way

   1. Under Device manager, Open sound and gaming controllers, now right click on your audio device (realtek)

                 Select uninstall, A pop up should appear asking to delete driver software, Be sure to place a check on the box.

   2. Restart the system and it should be back under device manager, Repeat step one and do this again until you only see High defitnition Audio under Device Manager, This indicates that you are running in a Generic Audio driver.


   3. Now to reinstall a synced Audio and Dolby driver.

Download this driver

Realtek Audio Driver for 64-bit Windows

And this time install this all the way thru.


restart the computer installation.

Now Open the Path that it gave you earlier, ex. C:/drivers/Realtek

  Look inside that realtek folder and look for a folder named Dolby or DolbyGUI

  inside that folder you will find installation files

     Dolby Advanced audio

     Dolby Theater

     Dolby digital plus


Install the one that came with your system and you should have it back


Let me know your findings
