That works for World of Warcraft, but SilentSpace's sig says he's playing LOTRO

Currently there is no way to do this that works for all games.
However... I have been meaning to do this for a while, so I looked into this and now have the capability built for Inner Space to be able to Mute or adjust volume of the game, the same as you can do through Windows using the volume mixer. Since it's using the Windows volume mixer, it will work differently for Windows XP than for Vista or later -- specifically, the Windows XP volume control is global and affects ALL programs, while the Windows Vista or later volume control is application-specific. So as long as you're on Vista or later, a
near-future ISBoxer version will solve this problem.

As far as new options in ISBoxer, these parts are not done yet and will take some time to get ready, but this is what I expect to implement:
- A check-box in your Character Set could be configured to automatically Mute when the window is background/inactive (even if ISBoxer is tricking the game into thinking it is foreground/active)
- Audio Control Action - This new Action could be configured to do any of a) Adjust (slide) the volume by some fraction, b) Set the volume to some level, c) Mute/Unmute
I should have something for you to try out this week.
