Lost sound

The problem is this, sometimes the sound is cut off or will disappear. Often there is a loss of sound for a second, for example when listening to music. Recently played mass effect 1, there's just craze some time the sound is lost, helped only restart the game. Also occurs during the roller hits on YouTube, the sound ustanavlivaetsya only when you refresh the page.
