Asus PT6 Deluxe V2 audio out to GTX295 HDMI

OK, this is how I see it but can someone tell me if I'm wrong. If I purchase a separate sound card SB X-F1 Titanium Pro (which I do not want to because the mobo has 7.1 built in) it has a TOSlink port to allow connection to the GTX295's TOSlink to allow pass through of the surround sound through the HDMI connector.
Since I have not purchased anything yet and do not have a PT6 mobo in front of me to look at and cannot see any literature on the product that describes such can someone who does tell me if their is an S/PDIF out port connection (two pin like used on the GTX) to link the audio from the mobo to the GTX295. The mobo does have an optical S/PDIF and coaxial connection what looks to be on the external connections (outside the computer case).

If you want your PC HDMI output to transmit the audio being generated by your PC (e.g. the audio from a video that you are playing), you will have to manually connect a cable from the SPDIF output from your sound card (usually a connector on your motherboard) to the SPDIF input located on your GeForce video card.

You will only need to make this connection under two scenarios. First, if you want to connect your PC to your HDTV and want the audio to come from the TV speakers for some reason. Notice that most people that have an HDTV also have a home theater receiver with a 5.1 or 7.1 surround sound and if this is your case, you don’t want the audio coming from the TV speakers, but coming from the surround speakers.

I'm pretty sure you have to connect a SPDIF out from the motherboard and into the GTX295 internally.
