No I don't think it is possible.  Since WMC is a MEDIA program it should be possible to tell it which audio output to use, so you can set the default output to the one you want your star trek sounds on and then tell WMC to use another output.  But I wouldn't be at all surprised if WMC did not let you do this.

Another option would be to find a little command line utility that can play a wav on a specific audio output and use Launch.

Sadly WMC always uses the default audio device.

So it would be finding a command line hack to play a wave file on the TTS USB Audio device as you mentioned...or for your app to play wav's to a specific sound device if it ever becomes easy/apparent.

Thanks sir!

I don't think it will happen in VC any time soon, but you never know.

VAC could probably help you with this issue as well.

May I ask what .net class you call to play wav files?

The program does not use .Net to play wav files.

If you know of a reliable .net method to play wavs which allows targeting a specific audio endpoint I'd be happy to take a look at it.  I think I'm currently using a win32 call to coreaudio because the .net method I tried was not reliable enough.

Well your right....i thought it would be adding an additional variable.

Basically, you would need to use DirectShow as described in this post.

Sounds like a lot of work to make this "simple" change.  Anyway, thanks for listening.
