I'm on High Sierra.
I've been trying to get the HDMI sound out of my GTX 760 with your guides but nothing seems to work.
I have a X99 Gaming 5P motherboard with integrated CA0132 audio chipset.
I don't have a DSDT because I don't really need one. Everything works perfectly on my Hackintosh expect for the sound.
The script audio_cloverHDMI-130_v0.5.command simply outputs:
EFI partition is mounted
Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem
Continue without HDEF/onboard audio (y/n): y
No audio codec detected
and dies.
I've tried to follow the instructions from here:
https://github.com/toleda/audio_hdmi_amd-nvidia/tree/master/ssdt_hdmi-nvidia
I've installed attached SSDT-HDMI-NVIDIA-BR3A with the appropriate changes for X99 , but still no sound.
I've also attached by IOReg.
Thank you!
