Okay this is something that has been problematic with Windows since Vista. Say I'm playing Borderlands 2 and I'm using a headset for the sound. I decide then that I want to unplug my headset and have the sound come from the speakers. I unplug it, but no sound comes out of the speakers for the game. They make sounds still, but the game doesn't come from it. And, if I plug the headset back in, I don't even get sound from that. This happens with other games too. How do I get a program to switch to a different audio output on the fly?
