Experiencing Bluetooth Speaker Issues on Windows 10? Microsoft Shares a Fix


Microsoft has published a support document explaining a Bluetooth issue introduced by the Windows 10 July 2019 Cumulative Update. The company explained that after installing this update (KB4505903) on Windows 10 May 2019 Update (version 1903) on a computer that has an internal speaker installed, you might experience one of the following issues:

  • A Bluetooth speaker can’t connect to the computer.
  • A Bluetooth speaker can connect to the computer. However, the speaker output sounds noisy (bad quality).
  • A Bluetooth speaker can connect to the computer. However, the sound is generated by the internal speaker instead of the Bluetooth device.

"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," the Windows maker added.

Microsoft has also offered a workaround to these issues in the support article updated over the weekend. Here is how to fix these problems:

To work around this issue, use the System File Checker tool (SFC.exe) to repair missing or corrupted system files. To do this, follow these steps:

  1. Open the command console by using administrative authority.
  2. At the command prompt, type the following command, and then press Enter:
    sfc /scannow
    Note It may take several minutes for the command operation to be completed.
  3. After the process is finished, restart the computer.

While Windows 10 1903 was largely free of bugs when it was introduced in May after months of internal and Insider testing, the cumulative updates delivered to the OS have managed to introduce quite a few bugs. They may be smaller and affect only a subset of Windows 10 users, but these bugs keep reinforcing the idea that the software maker is unable to deliver bug-free updates to Windows 10.
