Windows 8 and Windows 7 drivers are always compatible with Windows 10. So you can find the older driver by starting with Windows 8.

To find the driver, you can go to the audio device manufacturer’s website or the computer manufacturer’s website. It is recommended that you go to the computer manufacturer’s website first such as Lenovo, Acer, as they might release the audio driver which contains the Dolby audio driver. Please note that you need to use the specific operating system and the computer product name, model number or series number to find the driver.

    I am having the same problem on my Gigabyte laptop : The current Dolby audio driver version is 7.6.4.9 and the software application expects driver version 7.5.1.1. Please install a valid driver and software application combination. None of the above solutions have worked. Has any one got any other ideas?
