you can use the headphone jack on your laptop, if it doesnt have an audio out, which it should. Go to radio shack and get the right cable, should be a mini to rca, then you can plug the rca's into whatever equipment you want to play through.





If it doesnt have an audio jack or headphone jack, you can get the soundblaster audigy external, it's usb and will give you audio outputs.
