GTX 680 Audio in Mac Pro

[Kyahx]

I was hoping someone could help me with an EVGA GTX 680. This card is installed into a 2009 Mac Pro (MacPro4,1 patched with MacPro5,1 firmware for future CPU support) and being driven by the official Nvidia drivers (http://www.nvidia.com/object/macosx-304.00.05f02-driver.html) -- I would like to enabled audio via the HDMI port. I've read what I can on this board but my situation seems unique and would like some "expert" advice. I gather that I would need to patch my DSDT file using MaciASL and do *something* with IORegistryExplorer but I don't fully understand it all.

Any help would be greatly appreciated.
