Cousin Ken: Your last reply here seems to confirm what I stated in my original reply to you on this thread, that the Audigy 2NX probably doesn't include a 'built in' onboard midi sound card. If this is true, then Midi file playback (sound production) must be processed by your computer via a software program such as Virtual Sound Canvas, Microsoft GS WaveTable SW Synth (which I think is included with WindowsXP) and is selected via:

Control Panel > Sounds & Audio Devices > Audio Tab > Midi Music Playback: Default Device.

If the Audigy NX does not appear as a selection option, then this confirms the fact that it doesn't include midi support. You then must select from the other midi sound playback options: Virtual Sound Canvas, Microsoft GS Wavetable SW Synth, or other midi music playback selection option(s) available. Once you do this, your midi files should play thru Windows Media Player. In addition, you may want to select Windows Media Player as the default Player for .mid files as well: In Windows Media Player, go to: Tools>Options>FileTypes and place a check in the .midi file box.

Hope my explanation helps you solve your midi playback problem. Good luck.
