Sound system needs optimize

Everytime I load in WT, the sound of my computer will go off but only for WT(I can still watching videos), I have to reconnect my blue teeth or plug in my earphone again. NONE of my games have such a problem.
Today when I reset the background sound in a battle, the sound totally go off. you know how hard it is for a WT player to play in a silent world, and I was knocked out right after because I can’t hear the opponents’ engine.
I would like to ask gaijin that with your new version updated and new pack launched, do you have to add some bugs into your game? If you want to make a fortune, please respect your players instead of add more pack.

If you are sure the issue is not on your side (check your system sound settings, sound level adjusted for specific applications) please report bug here: Community Bug Reporting System
