T470s - no Dolby Audio support

Just got finished configuring a T470s, but I cannot get the Dolby Audio to function. All audio drivers are updated. I can see the Dolby Audio settings in the Lenovo Settings app, but there is no change in the audio when any selection is made on the panel. The Dolby settings panel does work on my T460s and the driver levels are the same. Any ideas here?


 UPDATE: SOLUTION::   I determined that the DOLBY modules never got installed. They are sitting in C:\DRIVERS\WIN\Audio\DAX2\x64. Running the installer using the REPAIR option restored the DOLBY support. I don't know why the installation was faulty from the preload.
