Hey guys, I had sound in the headphones inside the game. But, when I start to play, don't know why, the sound comes through the speakers and not trough the headphones. Is there something that I can do to fix it?

I think it would be strange if that were the game causing it.

Make sure your sound-card driver is set-up on the right way.

But I have this problem only with this game. In the other thousands of games/applications, it works properly. :(
Please help me :/

I just installed the most recent audio driver of my laptop and the directx posted in this forum. The problem remains.
Specifying it better. I had no problems playing it offline but when I enter the lobby at a network game the sound stops being transmitted though headphones and switch to the speakers. When I play that network game, the same.
I don't have any kind of audio problems in other application/game.
Please help me!

Try changing the Windows default sound output (or whatever it's actually called) to your headphones?

Uff, it is fixed!

I just disabled "Independent Headphones" at Windows Control Panel, despite "Speakers and Headphones" is and was always the default device. Weird but it worked ;)
