my elan kext brightness keys f11/f12 and volume keys are now working on Sierra after installing IOHIDFamily.kext from the beta 1 release...I also have intelbacklight kext and a dsdt patch enabled found on the creator's thread over at osxlattitude. I should have mentioned that this on a Gateway...

Hey, Once again I would like to thank you for your patience for allowing me to talk out my ???. I edited the kext that was previously edited for port 0x5. I will use a fresh kext if you feel it is necessary. I now have audio in both hdmi ports, and believe it or not, I still have sound when...

Sorry about the zip files...it was quite late. What I was referring to was this , when I connected to each port display 0 appeared under each framebuffer within the GFXO@2 code, I assumed this was the connected port. If I am correct the non audio port that is now connected shows display 0 and...

I was mistaken, port 7 hdmi appears to be the working one...providing I am reading the ioreg right. I was actually rebooting when I switched the ports (old habit), but I once again did as you asked, with the original mb kexts installed port 7 hdmi was the only working audio, the dvi port...

Hey, I have the z77n-wifi board with the i3-3225, I have tried to use the dsdt for hdmi audio but it keeps giving me a kernel panic. When I boot with -v it just loops with "invalid character found in processorOP". I have fixed all error and warnings but still have the same problem. The system...

I have been trying to use a dsdt for hdmi audio, but it gives me a kernel panic each time, when I use -v it shows an endless loop of "error in processorop". I have an i3-3225 processor on the ga-z77n-wifi board. Has anyone used this method with success? It may be something simple that this...
