Lenovo Z51-70 Dolby settings not activating after Windows update

After updating my windows to 1903 Dolby stopped working. Then I came to know that it was an issue with the windows update and licenses. So, I waited for the next windows update to solve the issue. But now my laptop received 2 cumulative updates to Window 10 version 1903 and Microsoft says that the problem is solved. But my laptop is still suffering issues with Dolby. What should I do now? Here are some images

If you have not done so yet, I would try reinstalling the Realtek Audio Driver. Lenovo bundles Dolby software with them.

 

Edit: If still no good try steps 8 and/or 1 of How to Fix asl.dll Errors.

Thanks for your reply. I have reinstalled the driver several times which doesn't help. Step 1 or 8 from the external link you provided also doesn't help.

To rule out it is not a virus or malware run a full system scan of your antivirus software or in case you do not have one other than Windows Defender download Malwarebytes. While your thaere download AdwCleaner also.

 

After that download and run Windows Repair to see if that can help clear up things.

This is not a virus or malware issue. It was working perfectly before the windows update. And after updating there was this issue. It is mentioned in the windows update section that it was a problem generated with a new version of windows. But the claim that this issue was solved with the later update. But after installing that update the issue remains.
