Hi, I've looked around for a solution but none have worked. I tried downloading some HDMI patch (1.1) but still the HDMI output in System preferences doesn't appear.
I updated the web driver but still no sound.

Any ideas?

Ok!

Down to the last step I think:

  1. SSDT-2.aml: (GFX0) AMD/Nvidia discrete graphics

Apparently this is the one I needed from ssdt_hdmi-amd:nvidia-PEG0.zip

I moved SSDT-2.aml to my Extra folder. There were no other SSDT.aml files in there.
Rebooted, didn't work. Tried renaming it to just SSDT.aml rebooted and still no HDMI in System Preferences/Sound.

Do I need SSDT.aml and SSDT-1.aml first before copying SSDT-2.aml ? If so, where do I get these files from?



Thanks in advance :)
