Deleted audio device

Hello,

The same situation happened to me. You have just to visit the 'add hardware' in the control panel. It automatically searches the uninstalled program or hardware in your computer/laptop. It would surely find what you have accidentally deleted device and automatically install it afterwards. Do not worry because the audio device of the computer cannot be completely removed because it is simply and practically part of your computer which can only be removed if one would literally plug it out of your computer.

Hope I helped you a lot. God bless you!
