      Dolby Advanced Audio does not start after updating the Realtek audio driver.



      If the audio driver from the Realtek Web site, not Lenovo’s, is installed in the system, the Dolby Advanced Audio may not start and may display the below error message.

      This issue may be caused by the version mismatch between the Dolby Advanced Audio and Realtek audio driver.  As the Realtek audio driver downloaded from the Realtek’s web site does not consider the support for Dolby Advanced Audio, do not use this.
