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.
