Hello, Currently I'm running 2 3d games. When I switch from one to the other the audio for the other (now out of focus) mutes. If 2d applications such as flash or windows media player are playing audio, the sound for the 2d app is played regardless of window focus but the 3d app will lose sound when out of focus. Is this a feature that can be turned off? In XP sound plays regardless of focus on anything but as I understand it the sound models changed between XP and Vista. This happens with my onboard sound and my PCI sound card. I have the exclusive rights check mark turned off in the sound options for the devices. Thanks in advance!  Just noticed if both 3d apps are out of focus both are muted.
