How to fix Bluetooth audio bug in Windows 10 May 2019 Update

If you keep your Windows 10 PC updated, you might have noticed that Bluetooth audio hasn't been working properly since cumulative update KB4505903 was released in July. This bug affects PCs with internal speakers, and if you regularly play audio over an external Bluetooth speaker, it can be a real drag.

Symptoms, as listed in Microsoft's support document, include not being able to connect a Bluetooth speaker to your PC, bad quality sound from a Bluetooth speaker, or audio playing over internal PC speakers instead of a Bluetooth speaker. Until Microsoft officially fixes the problem, there is a workaround you can try out to get Bluetooth audio working properly again.
