You can find it showing up in the programs list but not appearing on desktop icons. Whenever you launch the Dolby Digital Plus, error message reads, "The current Dolby Digital Plus audio driver version is XXXX and the software app expects driver version XXXX. Please install a valid driver and software application combination".


For most part, that malfunction has closely relationship with the audio drivers since Windows update always tries to replace the old drivers with the latest ones. While the Dolby Digital Plus audio driver may be incompatible with OEM audio driver, like Realtek Audio driver and Conexant Audio driver. To fix this driver compatibility issue, you have to download the matched audio driver for your Dolby Digital Plus or Dolby Home Theater. If you are trapped in that trouble, you can have a try with below solutions to retrieve your Dolby atmos which have been proved effective by many Windows 10 Dolby users.
