For what it't worth.

On our old crappy TV if I use the scart cable and connect the audio pin to
the line-in of my soundcard I hear the sound of the the TV channel that
was on before I switched to video input on the TV. (switch back to TV,
change channel, switch back to scart input and you hear the sound of the
new channel, but this could be our TV only :-)
It sounds strange but I guess the cable is somehow connected to the scart
audio out of the TV. I don't really see any use for it.
