Hi bryton63,
Welcome to Lenovo Community Forums!
First make sure that the Audio driver and the dolby will be in sync.
Open Device Manager
Uninstall the Audio Device Under Sound and gaming controllers / Make sure to place a check in the Delete driver software prompt.
Now make sure you don't have any dolby components
Proceed to Control Panel / Programs / Uninstall a Program
Uninstall all Dolby Related programs
Restart if Prompted
Now install this software driver
https://download.lenovo.com/consumer/mobiles/39z2010f.exe
When you install this software it will show you a directory path whre it will extract, Make sure to Remember the path
This next xtep is important
Open the directory path where the Audio driver installer extracted the Audio driver.
Check all the folders inside it and find the Dolby Installers, Install the Dolby either Advanced audio or Digital plus.
ANd you should now get your dolby back
Hope this helps
Cheers!
