Installing Windows 11 in full update install, Windows 11 overwrites Windows 10. Basically, drivers on Windows 10 are inherited and work on Windows 11 as well, but their advanced features are not sometime.
Uninstall Realtek driver, and apply Microsoft standard driver. There is trade-off as loudness equalization normally functioning or Realtek enhancements.
Loudness equalization is the choice of this post.
Realtek High Definition Audio
After updating to Windows 11, Device Manager shows Realtek is normally recognized. Settings also indicates normally, Sound on Control Panel provides Enhancements tab. It looks everything is working fine.
But switching on and off of loudness equalization, nothing change in sound. Apply button is not activated, too. It means that the driver is working fine, but enhancement is not.
Although appropriate approach is to install the latest driver, it is already installed in this case. Even reinstalling drivers has no effect.
In such case, uninstalling Realtek driver, and check whether Microsoft standard driver is applied automatically. And reconfirm whether enhancements are effective as expected.
High Definition Audio Device
Rebooting after uninstalling Realtek driver, Realtek is recognized as "High Definition Audio Device". Microsoft driver released at September 27, 2022 is applied. Settings also indicates normally. Revisit Enhancement tab in Sound on Control Panel.
