Actually, now that I think about it, I think the logic is like this:

pin  8 up = listen to a composite or s-video signal on this cable
pin 16 up = listen to a rgb signal on this cable

I'm not quite sure on which signal the audio is supposed to be switched
and what pin 8 down + pin 16 up is supposed to do.

How about if you jumper pins 8 and 16 together on the SCART connector,
does the TV sound cut off as it should?

Here is a spec of the SCART in different modes:

I think pin 16 should only be on when there is a proper signal on the
video card output.  If it is on all the time, the TV also thinks it's
supposed to show the signal all the time...
