Microsoft released the new Windows 10 update at the beginning of this month updating the Windows 10 installations to version 1809. This version brings many new features and improved performance, but some people have been reporting problems that after updating to version 1809, their PC is unable to playback any sound. Microsoft has looked into this problem and turns out that it was because Microsoft packed wrong device drivers for the Intel HD audio hardware. Because of this, audio was not working on some computers after the Windows 10 update. Some users were also getting the error message “No Audio Output Device Is Installed” and then the PC refused to play any sounds.
Microsoft has since released a patch that can remove the faulty device driver from your Windows 10 installation and after a reboot the audio should start working. This patch fixes the problem when Windows audio does not work after installing the Intel Smart Sound Technology driver (version 09.21.00.3755) via Windows Update or manually. Here is how you can fix the audio problem that paralyzes sound in Windows 10 after the October 2018 update:
- Visit https://www.catalog.update.microsoft.com/ in your web browser.
- Search for KB4468550 on the Microsoft Update Catalog website.
- Download the KB4468550 update and save it somewhere on your hard drive.
- Double-click on the downloaded file intcaudiobusremove_323cddf2aaa7369ece8f79c31eb00c941313627f.exe.
- Reboot your computer to enable the audio devices.
What this patch does is remove the faulty audio driver that is causing the problem. After the faulty driver is removed, you are asked for rebooting the computer. When you Windows PC boots up, it will be able to play sound properly. The patch is designed to work on Windows 10 version 1809, 1803 and 1709.
