Microsoft Suggests A Fix Windows 10 KB4515384 Bug That Affects Audio Quality in Games

Windows 10 Cumulative Update KB4515384 introduced a handful of issues in systems running May 2019 Update. There were numerous reports that the patch breaks audio in various games. The audio bug mainly affects games such as Apex Legends, PlayerUnknown’s Battlegrounds, WoW Classic, and Overwatch. Moreover, the players of other games experienced an extremely low volume.

After multiple reports, Microsoft has now acknowledged the issue in a support document. The company confirmed that a compatibility change in Windows 10 version 1903 was the major reason that caused the issue in the first place.

Microsoft has received reports that audio in certain games is quieter or different than expected after installing this update. At the request of some of our audio partners, we implemented a compatibility change that enabled certain games to query support and render multi-channel audio.

Microsoft further continued that the company has now reverted the compatibility change based on user feedback. The tech giant warned its users that the installation of the KB4515384 may trigger audio issues in some games.

Due to customer feedback, we are reverting this change as some games and some devices are not rendering multi-channel audio as expected. This may result in games sounding different than customers are used to and may have missing channels.
