FX1800 Audio to HDTV SPDIF Location Z800 Motherboard

HP Recommended
Microsoft Windows 10 (64-bit)

Trying to enable audio on my Z800  to a HDTV using the installed card quadro FX1800 via HDMI.

Z800 >Display port >Adpater >HDMI >HDTV .


My understanding is the only way to enable audio via HDMI from the sytem is connecting the 2 pin connector on the quadro FX 1800 to the (unknown if it exists) to the S/PDIF on the mother board. I cannot find the S/PDIF OUT on  the board.  Does someone have a diagram they can post. 


Also if the FX1800 can be enabled for sound via the display port in another way please advise. 


Z800 Product Number FL879UT


Thank you.
