This video shows you how to solve the “No Audio Output Device is installed”, or sound broken, audio broken after using Avast Driver Updater.
All you have to do is find the Driver that has “Sound”, and “Audio” word in its name. Then you restore all of them. In my case, I restored these four drivers

– Intel Smart Sound Technology Audio Controller
– Intel Smart Sound Technology OED
