Звук в игре через наушники. Как?

I had to use google translate on this post so I am sorry if I misunderstand anything you have said. It seems your problem is with the audio device that is selected. You need to make sure that the output device for Windows is the same as what you will use in-game. Once you select the device correctly in windows, select the same in game and hopefully that should fix your problem.

I hope this helps.
