The error above indicates that  the version of the audio driver and the dolby digital driver are different. Both of them must use the same driver in order for them to work correctly.


Try to:

3. Open Device Manager > Sound, video, and game controllers and check if the High Definition Audio becomes Realtek High Definition Audio or Conexant High Definition Audio (this indicates that the sound driver is installed properly).


When the audio driver is properly installed, install the DolbyAdvancedAudio and the DolbyHomeTheater from the following path:
