I can confirm it has worked on a Gigabyte P35-DS3... i dunno why it worked but it did. Just install CMI8738PCIAudioDriver kext in the usual way with the ALCinject.kext and AppleHDA.kext and the sound started working. Thanks a lot.
The mainboard is usually the sticking point of installation. Read through other peoples experiences with your board here: http://forum.insanelymac.com/index.php?sho...202&hl=ASUS Searching the forums is usually a good place to start. Search for "asus" under the hardware forum for more threads on you mainboard. If you are willing to get it going, you video card is well discussed when you search for it: http://forum.insanelymac.com/index.php?act...hlite=%2Bx850xt Andy
