I too have been facing this obnoxious sound bug whenver I’m in WvW or running Events. It sounds like a beeping noise, which just occurs in mass player enviornments. I thought it may be a sound card issue at first, however it seems that this is becoming the same issue for many players. The only solutions so far is just to restart the game, when I return the problem is fixed. The bad thing is that lately the bug is crashing my game. Are there any solutions to this problem Arena?
