A few moments ago, two new Realtek High Definition Audio drivers were spotted on Microsoft’s Update Catalog, namely versions 220.127.116.1159 and 18.104.22.16854, which might improve the system’s overall sound quality.
Regarding compatibility, the 8454 build is compatible with both 32- and 64-bit architectures of Microsoft’s Windows 10, including the Anniversary, Creators, Fall Creators, and April 2018 Update editions.
As for the 22.214.171.12459 version, this release is targeted at either 32- or 64-bit variants of Windows 10 version 1803 (also known as the Windows 10 April 2018 Update). Also, take into account that there are separate packages for each OS, so make sure to download the appropriate one.
With this in mind, save and extract the proper .cab file for your desktop or notebook configuration, go to Device Manager, right-click on “High Definition Audio Device” and select “Update Driver Software.”
Now, browse and select the newly-created folder containing the 8459 or 8454 audio build, and follow all instructions displayed on the screen for a complete and successful upgrade. Also, give the wizard permission to perform a system reboot to make sure all changes take effect properly.
That said, download Realtek HD Audio Driver 126.96.36.19959 or download Realtek HD Audio Driver 188.8.131.5254, carefully install the new version, perform a restart upon completion, and check our website as often as possible to stay up to speed with the latest releases.
