Small problem with adjusting volume in game

[linwig 0]

Hi guys, I normally play my games about 50% volume so I can hear people talking on mic better (Ventrillo etc). However it seems whatever volume I set in audio options in game is saved to the Wave slider in advaned audio properties in Control Panel. Is there anyway to set the 'effects' volume in game without it changing the slider in Sounds and Audio devices in the control panel? I like the wave volume in control panel to stay at 100% but Arma settings always seem to overide it.
