Update KB4468550 Fixes Audio Issues Caused In Windows 10 October Patch

If your Windows is updated to the latest Windows 10 October 2018 update then there  are chances that you might be facing audio problems , something along the lines of “No Audio Output Device is installed”.

The October 2018 patch caused this issue on many machines running Windows 10 version 1803 or above. Many users tweeted about this problem almost instantly as it was happening on such a wide scale when they realized that they Windows has stopped giving them audio when they start playing games, or launch a video player all while the sounds on their browser as well as the system sounds were working perfectly fine.

Since then Microsoft has rolled out update KB4468550 in which they have removed the faulty Intel Smart Sound Technology driver (version 09.21.00.3755) audio driver that was included in the October update.

“An Intel audio driver was incorrectly pushed to devices via Windows Update for a short period of time earlier this week. After receiving reports from users that their audio no longer works, we immediately removed it and started investigating. If your audio broke recently, and you’re running Windows 10 version 1803 or above, please check to see if the incorrect driver was installed. To regain audio, we recommend you uninstall the driver“, the company explained in their statement which you can read here.

But the automatic update to fix the issue did not came swiftly enough as some people struggled to fix their audio issues and had to rely on third party websites to release a hotfix patch to this error so they could finally have their missing audio back. Many have also complained that Microsoft should not force users to have automatic updates turned on by default because problems like these can be brought to light by users testing these live updates and can report them to Microsoft so the masses do not have to suffer.
