Update errors on Windows 10 aren’t anything new, with hundreds of different error messages stored in the Windows catalog waiting for the perfect time to flash across your screen. Although Windows 10 has had countless updates aimed at reducing the number of errors and bugs that appear, each and almost every new update seems to create a new problem.
Cumulative update KB4468550 is one such update that has caused some users to lose all sound on their system. The bug was simply caused by Microsoft forcing out an update with the wrong intel sound drivers, which caused a large percentage of users to lose all sound playback. Thankfully Microsoft has already released an update and fix for the problem, however, if it hasn’t worked or you don’t want to install another update that may cause issues, below you will find all the steps you need to follow to get sound working on your machine again. You can read the official Microsoft release regarding this issue below.
“An Intel audio driver was incorrectly pushed to devices via Windows Update for a short period of time earlier this week. After receiving reports from users that their audio no longer works, we immediately removed it and started investigating. If your audio broke recently, and you’re running Windows 10 version 1803 or above, please check to see if the incorrect driver was installed. To regain audio, we recommend you uninstall the driver.”

How Do You Fix Sound Not Working on Windows 10 After the Latest Update?
Even though Microsoft has released a patch for this careless fault, you may still want to manually fix the problem. You may also need to intervene if the patch doesn’t fix the issue on your machine. As the problem is simply an incorrect driver being installed on your system the fix is super simple. Uninstall the driver and install the correct one.
To begin, right-click the start menu and select Device Manager. Next find and expand Sound, video, and game controllers and look for a Realtek device or a device that has a yellow triangle with an exclamation point next to it. When you find it, click on it. Now click the View tab and select Devices by Connection.
Next look at the parent device, which will most likely be called something similar to: ”Intel SST Audio Controller" (Intel Smart Sound Technology driver version 09.21.00.3755)
When you find it, right-click the controller device, then choose Properties. If the driver version is 9.21.0.3755, you have the incorrect driver and need to remove it. To remove the driver click Uninstall Device, then follow the prompts to remove it from your system.
Once you have done that, close the Window and Restart your computer. When you start/sign back into Windows, the operating system will automatically download and install the correct driver.
