IOREG

[Elementrix]

I don't understand, but ioreg I think it has information about the sound

IOReg does not say anything about sound. Do you have sound?

Not the intent, remove files copied to ... patched
Run cloverHDMI (debug=0), restart. Post to AppleHDA HDMI Audio
HDMI audio is off topic on this thread.

Ok, moved my HDMI/ audio response to this thread.

All seems to be working.
I edited audio_cloverHDMI-130_v0.6.command and put back gDebug=0.
I removed the .aml files that I had previously manually copied to EFI..../patched. Rebooted. There was no HDMI audio device.
I re-ran . audio_cloverHDMI-130_v0.6.command, and everything seemed to go back the way it was in EFI..../patched except that the SSDT files had been renamed. I rebooted. I have HDMI device back in audio.
Result is the same as before the removal. I have HDMI on both HD630 and Nvidia Graphics. Not sure why you suggested that sequence other than my install is exactly as expected - file names etc.

Thanks so much for the help.

Not what you said in the onboard audio thread:

don't see a HDMI port out for either Nvidia or HD630

Not working

Not sure why you suggested that sequence other than my install is exactly as expected - file names etc.

Doing what you didn't want to do fixed what was not working for both Nvidia and Intel.
