Quite disturbing problem with audio device.

[4Rayden2]

I'm using the integrated audio device on my motherboard. Sometimes when I listen to something the audio just stops and when I check what's the problem windows either says everything is okay but doesn't still play anything or implicates that I have no audio device on. When I try to fix the problem via the windows standard fixing thingy it sometimes manages to fix it, for a short while (1-3min), reporting that "one or many audio service wasn't running". Also problem seems to occur more often when both front and back audio jacks are plugged in(headphones and speakers).
