The title might be a bit confusing, but if you face this error while installing or updating the Realtek audio driver, you will recognize it. Basically error code 0x000005b3 during the install of the Realtek audio driver indicates a problem with the driver installation, caused by the currently installed driver. The existing driver is corrupt, or partially uninstalled.

So how can you fix this Realtek audio driver install error?

The basic solution to this error is to uninstall the previous Realtek audio driver. That sounds simple, but the normal uinstall option is not always sufficient to solve the error.

The first step however is to run the uninstall from the Control Panel -> Uninstall (Vista/Windows 7) or Control Panel -> Add or Remove Programs (Windows XP).

Uninstall Realtek HD audio driver software

Once this is complete, you should open the Device Manager and check the entries under the Sound, video and game controllers. If there is still an audio device listed, uninstall it there as well. You can simply right-click the device and select Uninstall in the popup menu.

Uninstall Realtek High Definition Audio Driver device

If you see an option to remove the device driver files, select that checkbox as well before confirming the uninstall.

Remove Realtek driver software

In most cases this is still not sufficient, and the error persists. The steps that do solve the issue are to also remove the Microsoft UAA Bus Driver for High Definition Audio in the System devices category. So still in the Device Manager, open the System devices and see if this device is present. If it is, uninstall it in the same way you uninstalled the Realtek High Definition Audio device.

If the MS UAA Bus Driver for HD Audio does not want to uninstall, try disabling it first and then uninstall it. Simply right-click the device and select Disable in the popup menu. Then repeat with the Uninstall option.

Now reboot the computer and try the update or install of the Realtek audio driver again. You should no longer get the “install realtek audio driver failure” message with error code 0x000005b3.
