how to make input jack into an output jack?

[willryan42]

while simultaneously using the real output jack? i'm slowly getting into mixing, and i would like to have my headphones plugged into my macbook's input jack, and have my external speakers plugged into my output jack. is this even possible to do?

If you're getting into mixing you should buy external hardware. As for your question, I don't believe it's possible to do.

why not get a splitter? http://www.amazon.com/Belkin-F8V234...V2AW/ref=sr_1_1?ie=UTF8&qid=1287979053&sr=8-1

if you want to adjust volume separately for your headphones you can get a small amp for that line. maybe something like this http://www.astrogaming.com/products/detail/69/MixAmp/
