Microsoft has introduced an update to fix an issue that is causing some audio issues on machines running Windows 10 version 1803 or higher. The company has released the Windows Update KB4468550 which removes the driver that the company automatically rolled out from the system by mistake. Some users who have reportedly installed the update have encountered a problem that has completely muted their machines.

“An Intel Audio driver was mistakenly pushed into the device via a Windows update for a short time earlier this week. After receiving reports from users that their audio no longer works, we immediately removed it and began an investigation. If your audio recently broke and you are running Windows 10 version 1803 or higher, please check to see if the wrong driver has been installed. To restore the audio, we recommend that you uninstall the driver, “the company said in a statement.

Those who have not received the update can install it manually. To do this, type Device Manager in the search box, find and expand Sound, Video, and Game controllers, and see if the Realtek device has a yellow triangle with an exclamation point. “From the View menu, select the devices according to the connection and see the original device – it will be called something like ‘Intel SST Audio Controller’ (Intel Smart Sound Technology Driver Version 09.21.00.3755),” Microsoft said in its blog post. When you right-click on the controller device and select Properties, you should see a dialog like the one below. Click on the Drivers tab as shown.

If the driver version is 9.21.0.3755, you have a driver that was sent to you by mistake. Click Uninstall Device. You will also get a popup asking if you want to remove the driver. “Check the checkbox shown, so the driver will be removed. Then click Uninstall.” The company said. If the driver is uninstalled, you will need to reboot your system. Your audio (speakers and headphones) should work properly.

The development comes just days after the company began rolling out the new 2018 Windows 10 October update to its insiders. Microsoft Windows paused the October 10 update (version 1809) when users installed the latest software on their machines. They reported that their data, including profiles, photos, videos and documents, were automatically deleted after the update. The company later announced that it had identified the problem and fixed it.
