Recording from streaming input...

Headphone to microphone is one way of doing it, but you really should be using the line in socket, not the microphone socket. This is because the microphone socket is expecting a much quieter input, so it has a large amount of gain. So if the headphone socket, which is quite loud, is connected to the microphone socket, it could well cause a very loud and distorted input.

(Some computers which only have one "input" sockets that doubles up as both line in and microphone can automatically detect what kind of input has been connected and adjust accordingly.)

The other thing you risk here is causing a feedback loop, unless you have the settings right in your volume control. So you'd definitely want to make sure the "Microphone" control in the windows volume control is muter.

A possibly easier way would be to open the Windows volume control (if it's not in your system tray then do Start > Run > sndvol32 and hit OK). Click "Options", Properties, then select "Recording" and hit OK.



You should see a slider control for "What You Hear" or "Wave Out" or something along those lines. Make sure this control is selected (tick box at the bottom), then fire up your favorite recording software and off you go.
