Asked before and answered in a VERY detailed way (
) some time ago...
in short:
1) make sure you have a FULL DUPLEX soundcard (this means it can record and play at the same time; not all soundcards are full duplex!)
2) 2 ways of doing it:
* hardware-way: connect output to the input
* software-way: run duplex-software that records everything on your pc and streams that back

highly depends on what soundcard and sounddrivers you got...
