September 2019 Patch Tuesday updates are out for all major Windows 10 versions.

KB4515384 is plagued by problems

While the updates brought a series of security improvements, KB4515384 for Windows 10 v1903 already has a lot of issues ranging from USB errors to BSODs and graphics card bugs.

Now, a new issue with KB4515384 has surfaced up. Some Windows 10 users are complaining about sound card driver issues:

After latest windows update, realtek soundcard driver has disappeared. System restore to pre-update position also not happening. While doing restore, it is going on even for 10 hours without getting completed. No solution is working

This is not the first time when Windows 10 v1903 has problems with Realtek drivers. Same problem was encountered when Windows 10 May Update was first released.


No sound after Realtek driver update in Windows 10? Count on us to solve the problem.


This is not the only report, as other users confirm the same problem:

Im also experiencing issues with sound after september 10/11 update. […] I have deleted all windows updates which have been installed on september 11 that i was able to deleted and confirmed that these update were the cause of the problem.

How can I fix Realtek soundcard driver issues in Windows 10?

The issue might be caused by the new DCH drivers, but it’s not confirmed.

Taking into consideration the fact that restoring doesn’t solve the issue, you might want to try to uninstall all your current sound drivers and reinstall them from the manufacturer’s website.

If you want to completely uninstall your sound drivers in Windows 10, use the best uninstaller software from this article.

If the Windows default sound drivers are the problem, this solution might work for you.

After installing the new drivers, you’ll have to make sure that Windows won’t automatically update them in the future. To do that, follow the simple steps from this useful guide.
