    Hi all,

    I've a SAPPHIRE HD 5770 1Go in my Mac Pro 1.1. I play with this Mac on Win 7. Now i bought à PC for gaming and the Mac Pro take his place for his principal use (video editing, encoding film, photoshop, music...)

    So I use 5770 but i don't have sound with HDMI output. I think i need to install KEXT (driver) to resolve this problem. Could you explain me how to proceed (where download it and how to install) ? Thanks

    What do you think about to install a Yosemite or El Capitan on it ? I think this OS integrate the drivers for this card.

    Mac Pro 1.1 2x2,6Ghz (2006). Mac OS X10.7.5

    Since it's not an Apple card it's probably the flash.

    The Apple version of the HD 5770 doesn't have HDMI, it has Mini DisplayPort. And audio over Mini DisplayPort isn't supported either.

    Unless you're running a Mac flashed GPU in a MP5,1 you'll need that HdmiAudio Kext to enable HDMI/DP audio. I don't know if there's one for 10.7 though.

    I have a 1,1 and a Mac edition 5770. If you tell me where to look I’ll see what I can find?

    I'm on OSX 10.7.5.

    Maybe it's more simple to pass on 10.8 or ulterior to have HDMI audio output aviailable ?

    Get SFOT and marvericks or yosemite create a usb installer first watch the videos on youtube. Looks like a pain but its easy also do some reading and flash the card its not that hard either.
