Hi all,

I can't hear the in-game sound.
My hardware device works properly. I can hear any sound of each DVD game and even other browser games are running with sound. 
Strange thing is that I can hear the advertising sound left beside the game (Dart or Snooker).
The problem occurs with both browswer, inet explorer and Mozilla.
Clicking on the soundicon (loudspeaker) has no effect.
So has anyone an idea?
Thanks!
