Bttv and composite audio

I have a ATV-TUNER-F  tv card.
This is the manufacturer web site: http://advanteknetworks.com/products/tv … unerf.html

Here is some info of the card:

Tv-tuner video and audio works fine, composite video works fine but I have no composite audio (I'm using tvtime).
The adapter shipped with the card is very similar to this one:

but the usb connector on the picture is some sort of S-video like connector in my tv card.
