As a followup to this question: How do I use different audio devices for different apps in Windows 8?
I can play music from the XBox Music app on a different computer or network speakers via the devices charm in windows 8, but different audio devices attached to the local computer don't show up there. Is there a driver that can be installed, or a way to a configure local audio device to show up as a "play-to" device in the device charm?
