Me too face the same problem. After i update the audio driver below, Dolby App is gone 

Driver date: 1/16/2018
Driver version:

& the "Sound Enhancement" 4th tab in the Lenovo Nerve Center also gone.


After i rollback the Realtek driver, the app appear again. But system update will promtp to update the audio driver. The update remove the dolby app again.


Any one know how to get the Dolby Audio App back?
