Can't find anything in any forums about this. I often switch back and forth between the game and my online classes throughout the day, and I want to mute the background sound when I alt+tab out to another program. I know I can selectively mute programs through the audio icon in the lower right of the start bar (mini icon next to the clock), but that's pretty annoying to have to do that every time I switch back and forth, which tends to be quite frequent.
This seems like a simple feature and I don't know why there's no option for this in the game's settings menu. Most games automatically mute when you switch out. Anyone know how I can do this?
