Recently, there have been many complaints about the error code 0xC0000374, which occurs when Windows 10 users try to install the critical drivers of the sound card Realtek. Under normal conditions you should not see this error, but it occurs due to several software errors.

This error does not only occur with software errors but also indicates whether the system has a faulty soundcard installed. In such cases, the only solution for users is to change the sound card, because the software solution cannot afford to solve the hardware problem.

However, moving to a final solution is not ideal because you do not want to spend a few dollars on what may be a software error. We therefore recommend that you do a troubleshooting first to identify any problems with the software that may cause this error.

Activate the soundcard driver again

It is possible to install a damaged driver. In this case you need to cancel the driver installation and see if it will fix the error.

If restarting the driver does not solve the problem, proceed to the next solution.

Install the Realtek UAD driver cleanly

There is a high probability that your system has a faulty driver. This infected driver may cause this error. To install the Realtek driver correctly, follow these steps:

  • First uninstall the Realtek UAD driver using DDU (Display Driver Uninstall Utility) or the Driver Storage Explorer (RAPR).
  • Second, you need to download and reconfigure the Realtek Generic UAD driver installation.
