What's up barkerw.
Try this...
dj mixer Out to computer LINE IN (not MIC IN).
If you then can't get sound out of your computer speakers then check
START/PROGARMS/ACCESORIES/MULTIMEDIA/VOLUME CONTROL/OPTIONS/PROPERTIES/RECORDING
Enable all of you controls.
Make sure your LINE IN or AUX IN is not muted also observe your MIXED OUTPUT.
What program are you recording into?
Are you making a "mix tape or CD"?
If so, are you doing it straight through or are you editing it?

SPIN
P.S. How many OUTS do you have on your DJ mixer?
If you only have (1) set of OUTPUTS, then you might not want to split the signal.
Go OUT of dj mixer IN to computer. OUT of Computer IN to stereo system.
