Updating the audio driver to the most recent version ensures that the audio system is entirely compatible with the operating system and hardware and functions optimally.

The best way to update the driver is to download it from the OEM website. Most offer a digital assistant to identify the hardware and help you download and install the compatible version. If available, you can also download it via the Windows Update > Optional Updates section. Check if the Windows Audio Endpoint Builder is having a problem.

  • Expand Sound, Video, and Game Controllers, and then pick your Audio driver.
  • Once selected, right-click and select Uninstall Device. Windows will now uninstall the chosen Driver from your machine.
