KB5003173 is the cumulative update that Microsoft released included in the May 2021 Patch Tuesday cycle for 2 different Windows 10 versions, namely 2004 and 20H2, and merely as expected, it comes with important security fixes for those devices.

But while at first the installation of this update seemed to go as smoothly as possible, it now looks like KB5003173 is actually becoming a huge pain in the neck for some users.

Most recently, the Redmond-based software giant has confirmed that this particular cumulative update might cause issues for Windows 10 users with Dolby Digital audio.

Quite simply, installing this update on some Windows 10 devices could cause a high-pitched sound for many users, though Microsoft explains that nothing happens if stereo has been used.

"After installing this update, 5.1 Dolby Digital audio may play containing a high-pitched noise or squeak in a few apps when using certain audio devices and Windows settings," Microsoft explains.

Two workarounds

But as the company states that a full fix happens to be within the works, there's two workarounds you could try, including switching to a different app to ascertain if this behavior is going on there as well. The two solutions would be the following:

Streaming the video or audio in a internet browser or different app, rather than the app affected by this issue.

Enable Spatial sound settings by right clicking or long pressing on the volume icon within the notification area, selecting Spatial sound (Off) and selecting any of the available options.

At this time, no ETA is available regarding once the cumulative update problem might get a patch, but of course, you shouldn't hold your breath waiting for it. There's a chance Microsoft waits before the next Patch Tuesday cycle to release a complete fix, which means users would have to hold back until a minimum of June to get their on the job the full patch for this audio bug.
