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.

How to fix No Audio Output Device Is Installed error In Windows 10

CMD

#1. Open Command Prompt with admin privileges. To do so, select the Start button, type cmd and right-click Command Prompt from the list and run as administrator.

#2. In Command Prompt, type the following command:

pnputil /enum-drivers

Command Prompt Drivers

#3. A whole bunch of drivers will be listed and you will see something similar to the below message:

Published Name: oemXXXX.inf
Original Name: intcaudiobus.inf
Provider Name: Intel(R) Corporation
Class Name: System
Class GUID: {4d36e97d-e325-11ce-bfc1-08002be10318}
Driver Version: 08/22/2018 09.21.00.3755
Signer Name: Microsoft Windows Hardware Compatibility Publisher

#4. You would now need to locate the oemXXXX.inf name that is listed (XXXX could be any number). It’s worth noting that you’re supposed to find the right match otherwise you might remove the wrong driver and end up breaking another functionality of your PC.

#5. Once you have found the driver, run the below command from an admin command prompt:

pnputil /delete-driver oemXXXX.inf /uninstall

In the above case, oemXXXX.inf is what you had found earlier.

#6. This will solve your problem.

Method 2

  • Open Device Manager and select System Devices.
  • Locate Intel Smart Sound Technology driver (SST).
  • Right-click and select Update Driver.
  • Choose browse from the computer and select High Definition Audio.
  • Click Next.
  • Intel Smart Sound Technology (SST) driver will disappear and you should have Audio back.

Addressing No Audio Output Device Is Installed error on HP Windows 10 PCs

HP has acknowledged that there is a problem that may prevent the HP computers from using the audio system. The company has also shared a workaround that advises users to uninstall the wrong driver and restore the audio system. You can follow the third method below.

  • Right-click the Start button and select ‘Device Manager’.
  • Select System Devices.
  • Right-click Intel(R) Smart Sound Technology Audio Controller and select Uninstall device.
  • A uninstall pop-up message would appear and you can ignore the warning, and click Uninstall.
  • Click action in the top menu and click Scan for hardware changes.
  • Repeat this step again (if the option show ups).
  • If this issue persists, manually download the driver from the manufacturer’s website after uninstalling the audio driver.

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 09.21.00.3755).
  • 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 25.20.100.6326 which comes with Intel Display Audio Driver version 10.25.0.10 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.

  • Ajeesh M

  • Kisthuribai Basgaran

    Hi… I could not find Intel Smart Sound Technology (SST) driver in my system devices….

  • Adaryn

    Hi, I had this issue as well but it was NOT with the files listed. I wish I would’ve taken screen shots, but the issue with me was not with Intel Smart Sound — it was with Intel High Definition Audio and Intel High Definition DSP which were both labeled under “Other Devices” which is no longer listed on my device manager. What I did to fix it was roll back the file driver you mentioned (the Intel Smart Sound file) and uninstall the broken, incompatible drivers that were getting the error message (the one I rolled back had no such error so I don’t understand how that fixed the problem, not to mention it’s no longer there on my device manager so I can’t use the option 2 fix). My sound quality has drastically reduced because of this; it’s absolutely horrid.
