Plutonium

I am not able to hear anything entering BO2 MP & zombies. Although I have headset on default output/input device, volume mixer is 100%. Directx 12 is up to date. Volume in game is not muted.

Any assistance please? I tried everything and it is frustrating, before it was working just fine but when I reset my PC and re downloaded (following all instructions) it isn't working.

What should I change into what?

Yes, as I mentioned previously "Although I have headset on default output/input device". and yes it is already plugged in. Also audio is working on T5 but not on T6.
