Thanks for the update. That clarifies things a bit.
The line-out connection won't help things because you would need a line-in connection to do what you want to do.
Since that computer has iPhone headset support, a 3.5 mm four-pole to RCA cable such as this one should work. Amazon.com: HTTX 3.5mm Male Audio Stereo Jack to 3 RCA Female AV Camcorder Adapter Connector Extension Cable 90 Degree Angled 4 Pole 5-Feet: Industrial & Scientific
There are some available without the yellow video lead but you can usually ignore that connection if you can't find a cable without it.
