How to Fix ‘Intel Smart Sound Technology OED’ Not Starting Correctly

Some Windows users are experiencing a weird issue where their microphone and headphone functionality all drop at the same time. Upon investigating the problem inside Device Manager, there’s one particular service that seems to be causing the issue: Intel(R) Smart Sound Technology (Intel(r) SST) OED. This problem is confirmed to occur on both Windows 10 and Windows 11 and it’s most prevalent on Dell and Lenovo computers.

Intel Smart Sound Technology OED service – Not starting correctly

In case you’re dealing with the same kind of issue and you see the This device cannot start. (Code 10) or Failed to load external libraries as the listed reasons on why this service fails, there are a few fixes that other affected users have successfully used in order to fix this particular error code.

But first, let’s take a look at the most common culprits that might be responsible for these weird issues with the Intel(R) Smart Sound Technology (Intel(r) SST) OED service. Here’s a list of scenarios that you might be currently dealing with:

  • Outdated Intel driver version – One of the most common causes for this error (especially for users that are already on Windows 11) is an outdated Intel Smart Sound Technology driver. This problem occurs because the Windows Update is not yet equipped to fetch the latest driver versions compatible with Windows 11. To resolve this issue (on both Windows 11 and Windows 10), use the DSA (Driver Support Assistant) to install the latest driver version compatible with your motherboard.
  • Corrupted Smart Sound Technology driver – If you suddenly lost access to audio and audio recording, there’s a big chance you’re dealing with some kind of corrupted driver files. In this case, one way to deal with the issue is to uninstall the current Smart Sound Technology OED driver in order to force your OS to migrate to a generic equivalent.
  • Incorrect Smart Sound Technology driver – Keep in mind if you’re facing this issue on a Lenovo or Dell laptop, chances are you’ll need to install the Realtek driver in order to fix your audio issues. This is only a requirement for certain laptop models, but you can easily attempt this fix by downloading the latest Realtek HD driver and installing it to see if it ends up fixing the issue in your case.
  • OS Installation is missing some driver dependencies – Keep in mind that with certain PC configurations, you might need an additional Intel Media driver to ensure that your Windows installation is equipped to handle high-quality audio playback and audio recording. If the problem is occurring due to a missing Intel Media Driver, you can rectify the issue by installing the missing driver using the Microsoft Update Catalog.
  • Incompatible dedicated driver – If you’re already on Windows 11, there’s a high chance the issue will return promptly as your OS overrides the generic driver with an incompatible dedicated equivalent. To prevent this issue from occurring endlessly, you’ll need to use Device Manager to force your OS to stick with the HD Audio Controller driver instead of always going for the Intel Smart Sound Technology driver.

Now that you’re up to date with every culprit that might stop the Intel(R) Smart Sound Technology (Intel(R) SST) OED service in its tracks, here are a couple of methods that other affected users have successfully used to fix this issue entirely.

Update Intel’s driver using DSA

Before you move over to other fixes, you should start simply by ensuring that you’re using the latest available version of the Intel(R) Smart Sound Technology.

But our advice is to not rely on Windows (Device Manager or Windows Update) to figure out if you’re on the latest version or not. With the upcoming Windows 11, there’s a lot of segmentation affecting the fleet of Windows drivers currently.

The best method of ensuring that you’re using the latest available version of the Intel(R) Smart Sound Technology is to run the proprietary Intel DSA (Driver Support Assistant) utility.

Running this tool to help you to figure out if you’re running with the latest Intel drivers installed. If your driver fleet is outdated, this tool will Auto-update your driver to the latest equivalents using the official channels.

If you’re looking for instructions on using the Intel Driver & Support Assistant to update your Intel(R) Smart Sound Technology driver, follow the step by step guide below:

  1. First things first, ensure that no unnecessary applications or processes are running in the background. Also, close off any potentially conflicting tools like Nvidia Experience, AMD Adrenalin, Driver Booster, etc.
  2. Next, open up your default browser and visit the home page of the Driver & Support Assistant utility.
  3. Once you’re inside the correct page, scroll down under Intel® Driver & Support Assistant (Intel® DSA) and click on the Download Now button.
    Downloading the DSA utility locally
  4. Once the download is complete, double-click on the installer that you’ve just downloaded and click Yes at the UAC (User Account Control) to grant admin access.
  5. Next, check the box associated with I agree to the term and conditions and hit the Install button.
    Accepting the TOS and installing DSA
  6. At the next prompt, click Accept then click Yes at the UAC (User Account Control) and hit Install before waiting for the operation to complete. After the operation is finished, click on Launch and wait until the utility is open.
    Launching the Driver & Support Assistant

    Downloading the correct driver version
  8. Wait until all the browsers are locally downloaded, then click on the Install All button to install them.
  9. After every pending Intel driver is updated to the latest version (including the smart sound technology driver), reboot your PC one final time and see if you regain audio and recording capabilities once the next startup is complete.

If the issue is still not resolved, move down to the next potential fix below.

Uninstall the Smart Sound Technology OED driver

This method might seem counter-intuitive, but it’s actually one of the most effective things you can do if you’re currently having issues with the Smart Sound Technology OED service.

If you end up using Device Manager to uninstall the driver that is currently governing this service, you will essentially force your operating system to migrate to a generic equivalent. And since the issue is only reported to occur in situations where the Intel dedicated Sound Technology driver is used, you can expect the issue to be resolved entirely once your PC begins using the generic driver equivalent.

Note: Don’t worry about losing audio or recording capabilities permanently. You will only experience a brief interruption while your Windows computer migrates from the dedicated driver to the generic equivalent.

If you haven’t tried this fix yet, follow the instructions below to learn how to get rid of Inte’s equivalent of the Smart Sound Technology OED and migrate over to a generic equivalent using Device Manager:
