I normally have all of the in-game sound turned off via the sliders in the "Sound" options menu. However, if the game is running in the background and I switch it to it, the sound turns back on for a fraction of a second before muting again. This usually happens at an inconvenient time, such as when I'm casting Melt and the explosion occurs right when I bring up the window. It tends to be very, very loud, and people can hear it across the entire house.
Is there any way to keep it from doing this so I can switch back and forth from Tribes without having to turn my speakers down each time?
