Hi, I have an early 2009 Mac Pro which I flashed to 5,1 in the belief that it would enable me to put audio out over HDMI. I then found out that my card (geforce gt 120) would not allow audio out over HDMI. I had almost accepted that I would just have to make do with optical out for my new sound system until I saw it is possible to install non-EFI nvidia cards very easily. I am now trying to figure out if any of the nvidia cards will give me audio out over HDMI or are there no drivers for this? Any help would be very much appreciated.
