The Dolby Advanced Audio Error “version mismatch” – please install a valid driver and software application combination error indicates a miscommunication between the audio drivers of your system. It will show up from Dolby, however it most often appears when there is an error with Dolby and Realtek. In the most common case, you will notice that you have Dolby’s version 7.2.8000.14, and for proper functionality, you should have 7.2.7000.7. This is odd, as it basically asks you to have an older driver which is often not a god idea. A number of laptop manufacturers know about the driver conflict, but do nothing to solve it.
You might get this error every time you start Windows. Sometimes you simply dismiss it and everything is okay, but in certain cases you will get no sound from your system whatsoever. Even if everything is working properly, it is an annoying thing to have to deal with, and it’s never good to leave driver errors unattended.
Even though the manufacturers haven’t really done anything to solve this issue, a number of users have reported that messing around with the drivers, both Dolby and Realtek’s, has solved the issue for them. There is, however, a solution for this, so read on to see how you can get rid of this issue in no time.
Download Realtek’s driver from their website, then install Dolby’s driver
As weird as it may sound, the order in which the drivers are installed can actually mean a great deal. In this case, the first one to be installed should be Realtek’s driver. After that, head to the manufacturer of your laptop, or motherboard if it’s a PC we’re talking about, and download the latest Dolby driver for your model. After that, it’s time to remove everything and install it again.
The first thing you should do is uninstall your Realtek and Dolby drivers. Open Device Manager by pressing the Windows key on your keyboard and typing Device Manager, then opening the result. You will be presented with a list of all hardware devices on your system.
In the list, expand Sound, video and game controllers. You should see both the Realtek and the Dolby one here. Do the following for both:
- Click it
- From the Action menu on the top, select Uninstall
- Follow the wizard, and reboot your device when done.
At this point, both drivers are uninstalled and you should now install the ones you downloaded previously.
Go to your Downloads folder. Install the Realtek driver first. As mentioned previously, the order is very important. Reboot your device in the end. When done, install the Dolby driver, and reboot in the end. Your sound should now be working properly and you won’t be getting the error.
Windows drivers are somewhat of a hit and miss, and this situation only proves that. However, as with many other similar issues, the solution is fairly easy, and by following the steps in the method above, you will get rid of your problem in no time.
