A cumulative update released by Microsoft for devices running Windows 10 May 2019 Update, or version 1903, breaks down Bluetooth speakers, according to a support document published by the software giant.

Windows 10 cumulative update KB4505903, which was published on July 26 for Windows 10 version 1903 and Windows Server version 1903, causes Bluetooth speaker issues if an internal speaker is installed on a device where the patch is deployed.

Microsoft explains in the tech document (via WL) that there are three different glitches that could be experienced after installing this cumulative update.

First and foremost, a Bluetooth speaker might no longer be able to connect to the computer because of the cumulative update. Second, there’s a chance that the Bluetooth speaker manages to connect to the computer, but the sound it generates is of bad quality.

And last but not least, even if the Bluetooth speaker connects to the computer, it might end up being useless because the sound still comes through the internal speaker that is installed in the device.

“How to fix the bug”

The easiest way to determine if there’s a problem caused by this cumulative update is to check the Device Manager and see if the sound section warns of an issue with audio controllers.

“Additionally, in Device Manager, you notice an entry under the Sound, video and game controllers node for Microsoft Bluetooth A2dp Source that shows a yellow bang (exclamation mark) icon,” Microsoft explains.

The easiest way to fix the issue is to launch the System File Checker tool and perform a scan for corrupted system files. To do this, launch an elevated cmd.exe instance and type:

sfc /scannow

The process will take a few minutes to complete, and when you’re done, just reboot the device to complete the fix.
