I found a solution by myself. I was playing another game and suddenly I think some solution for this problem and that worked :), I JUST OPENED WINDOWS SONIC FOR HEADPHONES on settings. Write this solution everywhere, that can help other victims XD, btw your solutions didn't work but thank you for your help ^^

JBL Quantum 400 don't have Dongle for this reason I can't follow these steps and I think JBL QuantumENGINE causes this problem, because if I use headphone without JBLQuantumENGINE TruckersMP works good, but if I delete software my headphone not working good. Finally I want to tell you one more interesting experience, I was playing TruckersMP and suddenly electricity has gone off, the system kicked me offline but I am a laptop user I keep played without internet, then I quit the game and turned off my laptop. And the next day when I tried to open TruckersMP I started to get these problems.

I am using JBL Quantum 400, that's not wireless headphone I must use with cable already.

I am using JBL Quantum 400, when I open and start TruckersMP, before the profile screen all sounds crashes and game freezes then I close the game and I need to fix another problem, all sounds are goes wrong. I discovered something while I try to fix it, JBL Quantum software causes this, if you using JBL Quantum product it's ok but if you use it with that software, game(TruckersMP crashes Normal ETS2 working good)
