Windows 10 Audio System

Windows 10 October 2018 Update causes audio issues on specific computers with users reporting “No Audio Output Device Is Installed” error.

There appears to be an easy method to go back to a functional audio system as a Microsoft employee has shared a trick that would help you overcome this situation.

Several users have reported the issue on Reddit and as well as Microsoft answers forum. Similarly, there’s another thread on Reddit that documents a similar issue.

Windows 10 Audio Driver broken

The bug is affecting only a small number of devices as Windows 10 October 2018 Update has been pulled shortly after its launch. It’s also important to note that only a limited number of Windows 10 version 1809 installs are likely affected by the problem as the bug exists on certain Intel systems only.

A Microsoft employee has shared a workaround on Reddit and you can follow it to fix No Audio Output Device Is Installed error in Windows 10 October 2018 Update (version 1809).

Note: It turns out that the second method works for almost everyone so you can skip directly to the second method.

Microsoft offers a fix

Microsoft has acknowledged the audio problems on Windows 10 and the company has revealed that a botched Intel driver update was pushed out yesterday that disabled the audio system on certain PCs.

Microsoft says that the Intel audio driver was incorrectly pushed to devices and the company has already pulled the driver from Windows Update to investigate the reports.

It turns out that the bug also affects Windows 10 version 1803 or above and to fix the audio issues on your PC, you can follow the steps outlined by Microsoft.

Uninstall driver in Windows 10

  • Open Device Manager and Sound, video, and game controllers section.
  • Look for Realtek device or any other audio device that has an exclamation point indicating problems.
  • Click on the device and choose Devices by connection from the view menu.
  • Look for a parent driver called “Intel SST Audio Controller” (Intel Smart Sound Technology driver version
  • Right-click the controller device, choose Properties, click on driver tab and uninstall.

Intel responds

Intel’s support team has confirmed that the users might experience audio issues after installing KB4464330 for Windows 10 or Windows 10 October 2018 Update. Intel says that they have already identified the problem and Windows 10 October 2018 Update rollout has been paused on incompatible Intel PCs.

A fix for these issues is already included in latest Intel update and you can download Intel Graphics Driver version which comes with Intel Display Audio Driver version or newer.

You’re still recommended to install the latest version of Intel Graphics and Audio Driver which is compatible with October 2018 Update. For the time being, applying the above workaround seems to be the best bet.
