[SOLVED]No sound & cant play videos

Since Installing Bitdefender Internet Security 2020, I have no sound or am able to play videos of any format. The headphones work on another PC which I uninstalled BD and videos play as well.

System Specs -

GB B365M Aorus, Win10 Pro x64 - using Hyper-X Headphones with built in audio.

It was working fine before I installed BD?

Uninstalled Audio & GFX - Reinstalled Audio/GFX Done.
