I use a little boxes to sound and during the game i switched to headphones and the sound stop

I might be wrong - but isn't this caused by switching your sound device when the game is running? As far as I know multiple games (for example CS:GO) suffer from this. Restarting your game after changing your sound device worked for me in those cases.
Yes, see MC-44055.
You can fix it by doing F3+T to reload all resources.
