Can't hear the game

[Arkadi.Kr]

Hi guys, for some reason I can't hear the game.
In the very first seconds when the game being lunched I do hear the game but then after a sec when the mumble turning on I hear only the mumble w/o the game.

Any suggestions ?

Please and thank you.

I've never had this issue, and this might not work at all but it's worth a shot:

Click the speaker in your task tray (lower right corner of desktop), and select audio input. The tab to the right should be called something like "Communication". Select that tab and make sure you check "Don't do anything".
