If you recently upgraded to the Windows 10 October 2018 Update but you’re planning to roll it back due to audio issues, well, just have a little patience. You should give Microsoft a second chance as the company recently rolled out two important patches that address audio bugs on Windows 10.

Windows 10 KB4468550 and KB4468304 target two specific audio problems that usually affect Intel audio drivers and HP computer, respectively.

Here’s the official KB4468550 changelog description:

This update addresses an issue where after installing the Intel Smart Sound Technology driver (version 09.21.00.3755) via Windows Update or manually, computer audio may stop working.

Update KB4468304 adds the following improvements:

In working with HP, Microsoft has identified an HP driver with known incompatibility with certain HP devices on Windows 10 versions 1803 and 1809.  On October 11, 2018 Microsoft removed the driver from Windows Update to reduce the number of devices affected.  Additionally, Microsoft has released this update to remove the incompatible driver from devices pending reboot.  HP is actively working on this issue.

As a quick reminder, after installing the HP keyboard driver, version 11.0.3.1, owners of HP devices may experience the annoying  Blue Screen of Death error: WDF_VIOLATION. This is due to an incompatibility issues on certain HP devices running Windows 10 versions 1803 and 1809. Fortunately, now there’s a hotfix for this problem.
