Microsoft offers solutions for KB4515384 audio problemsTime: Sep. 17, 2019
Microsoft acknowledges that KB4515384 has an audio problem: it offers two temporary solutions.
KB4515384, a cumulative update for Windows 10 May 2019 (Version 1903), has been reported to have a number of issues since it was released on September 10.
Network adapter failure; There are audio inconsistencies in the game and so on. Now Microsoft has acknowledged the audio problem and offered a temporary solution.
On KB4515384's official support page, Microsoft acknowledged that this was caused by a "compatibility change" request from some audio partners.
Microsoft has taken steps to address the issue and is offering interim solutions to affected users. The "known issues" are updated in the support documentation:
Microsoft has received several reports that audio in some games is quieter or less harmonious than expected.
At the request of some of our audio partners, we implemented compatibility changes to enable some games to query support and render multi-channel audio.
Due to user feedback, we are in the process of recovering this change because some games and some devices did not render multi-channel audio as expected.
This can cause the game to sound different from the customer's habits and may lack a sound track.
Microsoft says the solution is to fix audio problems by disabling multichannel audio. Before the official release of the patch, currently affected users have two solutions: one is if the affected game has relevant
Settings, you can choose to disable multi- channel sound;
The second is to search for third- party audio device control Settings in the Windows control panel and disable virtual surround and multichannel audio.solutions
