I'm wondering if anybody else is having this weird issue with ingame sounds?
I wrote this bug report, so please tell me if you got something like it:

"I\'m still having the same sound issue than I\'ve got in the end of previous beta phase.
I\'ve got a laptop and outer speakers plugged in and headphones plugged in those speakers. When I launch the game, no problem, but when I join/start a game the sounds starts to come out of my laptops speakers. It is a weird situation and it doesn\'t happen in other games. Somehow the game puts my laptops plugins off. I\'ve tested it many ways and I can\'t fix it, so you need to do something. I can\'t remember when this happened first time but it was after the update just before previous phase ended. Oh, and I also tested to join a game, ALT+TAB to my browser and put something to play on Youtube and sounds still came out of laptop\'s speakers. It played a minute and then it got muted. I checked the game and I noticed that I got kicked out of game because of inactivity and sounds came back to normal! Please try to fix this, I can\'t enjoy playing with this annoying thing..."
