For those unaware, Microsoft had released the optional Windows 10 KB5000842 update on March 29, 2021, as part of the March 2021 update cycle for PCs running v20H2 and 2004. This optional update was released to address several issues with the operating systems including problems with dark screens and other monitor glitches, video playback, as well as system crashes due to deletion of files and folders that OneDrive syncs. Ever since KB5000842 has been released for Windows 10 users, it has caused problems like game performance. Not only this, it is now causing high-pitched noise issues. According to Microsoft, Windows 10 KB5000842 update is causing ‘high-pitched squeaking’ noise for Windows 10 users while using some 5.1 Dolby Digital audio configurations. “After installing KB5000842 or later updates, 5.1 Dolby Digital audio may play containing a high-pitched noise or squeak in certain apps when using certain audio devices and Windows settings,” Microsoft explains on the Windows 10 Health Dashboard. The company has acknowledged the issue and clarified that it is only occurring on 5.1 surround sound. The problem does not occur on systems where stereo audio is used. The affected client platforms due to the high-pitched noise issue are Windows 10 version 20H2 and Windows 10 version 2004. Meanwhile, the company has recommended the following workarounds to users to mitigate the issue until a fix is released:
Streaming the video or audio in a web browser or different app instead of the app affected by this issue. Enable Spatial sound settings by right-clicking or long-pressing on the volume icon in the notification area, selecting Spatial sound (Off), and select any available options.
Microsoft is working on a resolution and will provide an update in an upcoming release. Source: Microsoft
