Download & Fix Dolby Audio Driver for Windows 10 for Lenovo Notebook

Upon upgrading to Windows 10, Lenovo Notebook G series users are facing issues in their audio driver which is surprising as since Windows 8, Microsoft have been able to add most drivers in their core for audio especially. However if there is a problem, there is a solution. The problem being faced here is whenever an effected user turns ON laptop, he gets a pop-up with error from Dolby Advanced Audio i.e. “Unable to start the audio driver. Please restart the computer or reinstall the driver if the problem persists“. This problem occurs every time when you turn ON your laptop or restart it.

  1. Thanks. After many times reinstalling the Realtek drivers, your fix seems to work on my t450s. So far, so good. I even had the Lenovo techies at the house, but no go. It may have worked this time because I deleted the software in addition to the drivers. I’m just not sure. I thought it worked, last night. When I streamed a movie, today, still the same results, dolby turns off if I click on another program. Thanks, anyway.
