Um, let me set the record straight here. There is no impedance problem
with using a headphone out jack as the imput to a soundcard. Since most
modern electronic inputs are voltage not current mode devices, you want
the output impedance to be at least 10 times less than the input
impedance. A headphone amp will have a very low output impedance, and
will have absolutely no trouble driving your input.
HOWEVER, C.R.P. is completely correct that a headphone output is not your
best choice. Usually they are pretty noisy, which isn't a function of
impedance here, but gain staging / cheap implementation.
Best thing to do? Try it, and yes Radio Shaft is probably the place to
look for cables.
A "Tape out" jack on your stereo is what you're looking for anyway.
Good luck, and I hope it doesn't seem like I'm jumping on this one.
