No Sound

well i went to 20 without sound, but now i kinda really want it pretty bad. I dont seem to understand, my sound works fine in my other games and in my computer. It even works fine in the Guildwars menu and login screen. But when i login in to play, my sound cuts off compleatly. Sometimes it will even play the sound perfectly when i login and play, but those are very few random ocasions. And after awhile when i zone the sound will cut off to nothing as well too. I dont know what to do, help me.

-Deckose
