Audio output back to mike

[dBFX7532]

I have a sheet music program (E-Stand) which records from the microphone and plays back while the music is dispayed. Is anyone aware of cables or electronics and corresponding settings which allow the audio output from a playback program (such as MS Media player) to be redirected back into the microphone input at correct levels and impedences? The computer is a Gateway M280E convertible notebook 2.13mHz. The jack for the mike and phones is on the front of the laptop. There is a PCMCIA slot available.

My understanding of this problem is:

MIC -> MUSIC PROGRAM
MUSIC PROGRAM -> SPEAKERS
WINDOWS MEDIA PLAYER -> SPEAKERS

You could get your music program to record from "STEREO MIX" or "WHAT YOU HEAR". This will record everything you here in your soundcard.

You then have to make the microphone audable in the playback settings.

All of this can be done from the Volume Properties (or just type sndvol32 in START -> RUN).
