routing audio through NVIDIA Geforce 9500 GT

Can i route the audio through the HDMI connector of the Geforce 9500GT?

So far I used the DVI output and the audio Jack of the PC.
Now I want both to go through the HDMI output.

Is that possible?
I don't see the HDMI at the control pannel of the Win 7.

 

If at all possible you probably have to connect your soundcard with the gpu through an SPDIF cable.

 

It is working now.
The problem was that the SPDIF cable was wrongly connected to the SPDIF_IN on the motherboard.
Once I connected it to the OUT, it is working.
