KB4556799 Windows 10 update causing Audio issues; here is how you can fix it


How to fix the KB4556799 audio issues in Windows 10 PC/laptop

Microsoft released the Windows 10 KB4556799 cumulative update last week. This cumulative update has many security fixes for Windows 10 versions 1909 and 1903. As is the habit of Microsoft, this patch brings with its own set of problems for Windows 10 users. We had already written about how the Windows 10 KB45556799 gave error code 0x800f0831 and 0x80070308 and failed to update for some users.

Now it seems that the KB4556799 is also affecting audio on many PCs/laptops. The Windows 10 KB4556799 update is causing audio issues and temporary data loss for many users. A Windows 10 user reported that this update resets audio driver configurations and removes Realtek audio driver. Others reported that their laptop lost sound after updating the KB4556799 patch.

With This Update, My Audio Devices Have Been Completely Broken. I Have Realtek Audio Drivers And I Can’t Play Anything Via The Speaker And Even The Headphones. I’m Experiencing The Problem On My Desktop And Surface Pro 6. I Clicked On The Sound Icon And Initiated Troubleshooting, Which Said That Audio Enhancements Couldn’t Be Loaded. I Uninstalled The Update And Audio Is Now Back.
