Windows 10: How do I reinstall a lost driver?

AVG driver updater recently ran a scan and updated a few drivers - Now my sound bar says that there is no audio device installed. I have checked in control panel under Sound, there is no driver for audio left. Yes, I have restarted my computer to see if it reinstalled it automatically.

3. Right click on the device and then select "Uninstall".
