I have GeForce 9600 GT 1GB but i cant take sound with HDMI cable

İ just changed my video card. I could take sound from my ex-card with hdmi cable to my lcd tv. But with this new card i cant. How can i fix this. My new video card is "palit geforce 9600 super+ 1gb". And i plug yo audio cable from my motherboard to video card.

Right next the SLI connector on the card you should see a small white 2 pin socket.
With the card you should also have a small cable (S/PDIF) with the corresponding white plug at one end. That fits into the white socket and the other end which has two single black pins attaches to the S/PDIF out header on your motherboard.
Once this connected up you will have sound over HDMI.

On this page http://tech.icrontic.com/articles//palit-9600gt-hd3850/2/ , the cable is shown (along with the other accessories) in picture 2 -the thin cable on the left.
