Yesterday we reported on users experiencing issues with audio playback after being sent a driver update over Windows Update for Intel Audio Controller, in which Microsoft commented and provided a guide on how users can uninstall the update.
Now, Microsoft has gone ahead and released an actual fix. The update is available via Windows Update for affected systems, as KB4468550. Microsoft summarises the issue on their support article for the issue:
This update addresses an issue where after installing the Intel Smart Sound Technology driver (version 09.21.00.3755) via Windows Update or manually, computer audio may stop working.
If you’re affected but haven’t received the update automatically, it can be obtained manually from the Microsoft Update Catalog.
