Any help please for #2300 (https://www.tonymacx86.com/threads/audio-hdmi-audio-applehda-guide.143760/page-230#post-1431042)? Am I missing a file or some info in my post? Thanks.

HDMI audio does not.

Apologies, missed your post.
IOReg shows HD530 HDMI audio is working.

I'll give it another try, thank you.

I have a strange problem - my HDMI Audio stopped working overnight. It was working perfectly as it has done since Sierra was installed very soon after its release. I have tried removing the SSDT rebooting and re-running the installation script but I still get no audio.
EDITED TO ADD - Computer was shutdown overnight not asleep.

I have noticed for the first time another unusual behaviour if I try and use either Clover Preference Pane or Clover Configurator to auto load the EFI partition it does not work - I tried as I was troubleshooting today. I have to load EFI Partition manually. I also notice that the disk on which Clover reports the EFI partition can change - not on every boot but on some. e.g. sometimes on disk1s1 or disk3s1 or disk4s1. The boot media is a Samsung M.2 SAMSUNG MZHPV256HDG. Might be a red herring but odd I should notice this around the same time.

I have removed extra Clover Boot Entries but the had drive behaviour remains.

Below is the requested problem reporting info - I could not supply the Console Output as my Console gives me no option to save or save as under file. I have never used Console and could not figure out how to display (last boot) tried google but found no reference to displaying All Messages since Last Boot. I am probably missing something simple due to never using it before.

se either Clover Preference Pane or Clover Configurator to auto load the EFI partition

Not recommend, use Community Software/EFI Mounter v3

the disk on which Clover reports the EFI partition can change - not on every boot but on some. e.g. sometimes on disk1s1 or disk3s1 or disk4s1.

Always true, use Terminal: diskutil list to determine disk#

HDMI Audio stopped working overnight

Do not see any problems. What it the connected HDMI device?

I have one question.... i attached all needed files as requested. I just use you SSDT-HDMI-NVIDIA-BR3A.aml and had to find BR3A and Replace it with BR2A. (As i understand my GFX is found there.) Now OS X sees HDMI and HDMI is selectable as output Device too. But if i play sound i can not hear anything. Can you tell me a reason for that?

I do not use a patched DSDT, only SSDT for Powermanagement und for HDMI Audio (your source). AppleHDA is vanilla. Nvidia webdrivers are installed and working. Monitor is connected per HDMI.

that is the problem, I couldn't see any issue either.

Now I have just returned home and powered the computer on and as if by magic the Audio is back. If it happens again I will post back. I did not do anything to resolve except run Onyx permissions repair and cleared caches followed by yet another removal of previous attempt and re-application of your script. again.

Thank you very much for your time and attention - frustrating not to know what caused it but glad its working
