No audio output device installed

Windows updates are known to add new features, fix bugs and improve user-interface, but that’s not the case anymore.

The last few updates of Windows 10 caused many troubles for users. A few years ago, I used to download and install every update at the moment I see them. Now, I started reading reviews before installing any update just to avoid any unwelcome issue.

After the Windows 10 October update, many users are facing “No Audio Output Device is Installed” error. Yes, the update was released two months ago but not every user updates their OS at the same time. So, a lot of users are still facing this audio issue while adjusting the volume.

Today, I will explain two methods that have worked for many users to fix no audio problem in Windows 10. The first one is a user-proposed method while the other is offered as a fix by Microsoft.
