Wouldn't this be simple to accomplish by having a device selection in the USB phone application? I know this seems simplistic, but it seems there have been so many things taken out of the end-users hands that we are now left trying to program around an array of limitations instead of trusting that the user really does know what they are doing. Alternatively the OS would have to remember the "default" audio device for each application independently. Thank you, David A.

We only want the speaker in the phone to sound when a phone call is coming in or you are actively engaged in a phone conversation. Meanwhile the regular PC speakers play back the usual dings and dongs and perhaps a little Mozart? -Chris Perry From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Tim Roberts Sent: Thursday, May 14, 2009 12:42 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: Need USB Audio device to not be the default speaker at plug-in Perry, Chris wrote: Suppose I am developing a USB based toy gun that comes bundled with a game. When the user plugs in the USB gun, the ultimate user experience would be for the game application to launch and only render gun sounds sent from the game application. Ideally I don't want the USB device to show up as a device that a user can select for as a generic speaker using the control panel applet. Why not? I mean, what's the worst case scenario? Some 14-year-old would think it was cool to have music playing out of his gun, and then he unplugs it and goes back to his normal audio device. I just don't see why this is a situation that is worth worrying about. You wouldn't MAKE yourself the preferred device, but if some user wants to do so, he gets what he deserves.
