This post will introduce four mostly used ways to help you fix the problem.

Method One: Roll The Audio Driver Back to Previous Stage

Judging from the different version numbers noted on the notification, it is suggested you try to roll the audio driver back to its previous stage first.

Here is how you could do it.

2. ExpandSound, video and game controllers option and right click your audio device and chooseProperties .

3) UnderDrivertab, chooseRoll Back Driverand then chooseOKto save the change.

4. ClickYes. 5) Wait for a couple of seconds for the system to help you with the process.

Then you should be able to see the notification asking you to restart, please clickYes for the change to take effect.

6. After the restart of your computer, please check and see if the problem still persists.

Note: If theRoll Back Driveroption is grey, that means you could not do this procedure as planned. you need to perform other operations for the problem to go away.

Method Two: Uninstall Dolby From Device Manager

1. Open Device Manager . 2) ExpandSound, video and game controllersoption. Right click the audio devices on your computer and chooseUninstall. 3) Confirm the option by clickingYes.

You may need torepeat this procedure with Realtek or Conexant or some other audio device and Dolby audio device.

4)Rebootyour computer after this so Windows can update the correct drivers for you.
