Microsoft is working on resolving a high-pitched noise issue Windows 10 users hear when using some 5.1 audio configurations after applying recently released cumulative updates.

"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.

As the company adds, the newly acknowledged issue does not occur on systems where stereo audio is used.

The high-pitched noise issue only affects the Windows 10, version 20H2 and Windows 10, version 2004 client platforms.

Microsoft is currently working on resolving the known issue, with a fix to be delivered to affected systems in an upcoming release.

Until the audio problems are fixed, Redmond provides the following workarounds to help impacted users mitigate the issue:
  • 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 fixes high-pitched noise bug in Windows 10​

Microsoft has fixed a known issue causing applications to play high-pitched or squeaking noises while using certain apps in Windows 10 2004, Windows 10 20H2, and Windows 10 21H1.
This week, Microsoft released the Windows 10 KB5003690 preview cumulative update, which now fixes this audio bug for affected users.

As the KB5003690 update is an optional update, Windows 10 users will only receive the fix if they manually perform a 'Check for updates' in Windows Update and install the update.

Those who do not wish to install the preview update can wait until the mandatory July 2021 Patch Tuesday updates to receive the fix.
