When Microsoft found that some devices were not ready for Windows 10 version 2004, it moved them to a compatibility level. This is usually done to preserve the user experience.

However, avoiding Microsoft’s compatibility lock isn’t always a guarantee that a device won’t have compatibility issues with the Windows 10 May 2020 update. It’s a harsh reality that some users have to accept after the operating system has caused sound problems on their computers.

Complications with sound in Windows 10 2004 date back to a pre-release version of the operating system. A few months ago, a Windows insider said on Reddit that his system lost sound after upgrading to the beta version of Windows 10 2004. Now the affected machines had to be compatible with Windows 10 version 2004, so Microsoft offered them iOS first.

The good news is that some of the affected users resolved the problem after troubleshooting their audio devices. Similarly, the sound card driver update seems to be working for others.

Why does audio stop working after a Windows 10 2004 update

As mentioned earlier, a corrupt and incompatible audio driver usually causes audio problems, especially after the latest Windows 10 update. Rolling back or reinstalling the audio driver with the latest version is a very helpful solution.

Lack of sound from your laptop’s speaker is a common problem, especially after the recent Windows 10 update, a number of users report no sound from their system’s speaker.

The most common cause of this problem is an incompatible and corrupted audio driver. There are other reasons, such as the fact that the November Windows 10 update changed your microphone privacy settings, so apps that used to have access to it no longer work and the microphone doesn’t work.

Sometimes external speakers can be the reason you’re reading this article on how to fix Windows 10 sound problems. Be sure to check them on a device other than your Windows 10 PC.
