10.6.5 and up have the drivers built in. Only Windows will need anything downloaded.

Thank you kaz-k for your help. My HD 5770 doesn't appear to have a minidisplay port. It has 2 x DVI and 1 x HDMI. I've tried connecting to my tv via one of the DVI to HDMI, but for some reason I still can't get sound from my tv, although I am getting sound from the mac?
Perhaps there is something I still need to do to use my tv's built-in speakers?
Thank you again for you helpl

Thanks DieselFuelForLife for responding to my plea. As I said to kaz-k, I'm still trying to output sound to my tv with no luck so far.

As was said before, OSX does not support audio out of the 5770.

A 5770 that does not have Apple EFI firmware will not show a picture under Mac OS X.
A flashed PC card may not show anything until the login screen (or at that point in time when Mac OS X is fully active).
Who knows whether the non-standard card you have can support sound through the interface. If it is not showing up, you will probably have to hook up the headphones output with amplified speakers.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers
