If, when you try to install the necessary drivers for your Realtek sound card and you receive the error message: Installation of the Realtek HD audio driver failed, error OxC0000374, this message is intended to help you. In this article, we will try to identify the possible cause of the error as well as provide you with the appropriate solutions that you can try to help you resolve the problem.

When the driver installation fails, you will receive the following error message;

[Error code: OxC0000374]

Note that the error code may be different, but that is another instance of the error, and the solutions presented in this article also apply.

This problem can occur in several scenarios and there are several possible causes. However, there are cases where this problem occurs due to an inactive sound card. This situation cannot be resolved by a software solution and will require you to replace your sound card. You’ll see no errors and an unknown device with a yellow exclamation or question mark in Device Manager, and Windows 10 won’t allow you to install drivers because the hardware device is dead.

None of the solutions in this article will work if this is the case.

The driver installation may be corrupt. In this case, you will need to restart the driver installation and see if that resolves the error.

If resetting the drivers does not resolve the problem, continue to the next solution.

  2. Press M on the keyboard to open Device Manager.
  3. From inside the Device Manager window, expand the menus and find the audio drivers.

3] Use the Add Legacy Hardware option in Device Manager

This solution is only applicable when the audio, video, and game drivers are missing in the Device Manager.

To add the legacy hardware option in Device Manager, follow the instructions in the guide provided earlier in Solution 1.

If you still encounter the error, go to the next solution.

4] Disable Microsoft UAA bus driver for high definition audio

Since Realtek is the only audio driver that comes with installing the UAA driver inside, unlike the Conexant od SoundMAX drivers, you can disable the UAA bus and reinstall the driver. Since the conflict is in the UAA driver, removing it will allow Realtek to install properly, along with the UAA bus.

To disable the Microsoft UAA bus driver for HD audio, follow the instructions in the guide previously provided in Solution 1.
