I don't know the exact position but it must be near the audio output socket 
where there is a 10 pin connector looking like this:
              (1)-> . . . . . <-(9)
                    . . . . . <- ground
Now the first pin (1) in the upper row is the left channel and the last pin (9)
in the first row is the right channel. All the pins in the second row are wired
to ground. You can use these pins and connect them to a stereo socket that you
can connect to your HiFi set. You should use a shielded wire!
Hope this helps,
                   laci
