OK, we're getting closer.

In the Windows Control Panel, Sounds and Audio Devices dialog, Audio tab, 
there is a "Sound playback", "Default device:" combo box. Set that to what 
you want and plain -odac should work. Otherwise, uncheck the "Use only 
default devices" checkbox, and -odacN option should override the default.

Hope this helps,
Mike
