Hi!
I am having an issue with HDMI audio on a dual boot OSX Catalina and Windows 10 on an HP Z420Workstation.
OSX works great just like Windows, the problem is when I go from one system to another REBOOTING.
The sequence is the following:
1 – I turn on the computer and enter OSX with the picker, ALL NORMAL, RESTART
2 – Enter Windows 10 with the picker, ALL NORMAL, RESTART
3 – Enter OSX again, I DO NOT HAVE HDMI AUDIO, works fine through the audio ports of the machine
If I turn the computer off and back on the HDMI audio is restored.
Doing several tests I have noticed that when I restarts and goes from one system to another its like the previous one remained in Suspend/Hibernation, how did I come to this conclusion? Because is another of the symptoms with Google Chrome, although it works ok, when I try to close it its stops responding, googling I see that it is one of the symptoms that happens on some computers after returning from hibernation, like the loss of Audio. Obviously I have hibernation disabled on OSX.
The audio through the computer ports (not HDMI) works perfectly.
Next, I leave some specifications and solutions that I tried without success
Equipment: HPZ420 Workstation
Video card: Radeon RX580
Opencore: 0.9.0
Audio codec: Realtek ALC262
To perform the hack guide me with the following guide:
github.com
List of SSDTs I'm using
SSDT-CPUPM
SSDT-EC
SSDT-HDEF
SSDT-HPET
SSDT-IMEI
SSDT-OTHERS
SSDT-SBUS-MCHC
SSDT-USB2
Kexts list:
Lilu, VirtualSMC, Intelmausi, mXHCD, RestrictEvents, USBToolBox, UTBMap, WhateverGreen, AppleALC, CpuTscSync, SMCProcessor, SMCSuperIO
Some of the things I tried and didn't work:
1 - OpenCore NO ACPI (do not pass APCI info to Windows)
www.olarila.com
2 - These options to TRUE in the config.plist
UEFI/Audio/ResetTrafficClass and
UEFI/Audio/DisconnectHda
3 - alctcsel=1 in bootargs
The last thing that I am trying to test is the use of a kexts called CodecCommander.kext which I would not be understanding correctly how to activate since it is not done just by putting it in the kexts folder and adding it to the config.plist, I don't know if it will work either. solution, if someone can enlighten me here, I leave the link
github.com
I don't know if I was missing any information, if so, just ask.
Thanks in advance!

OpenCore NO ACPI - How to use this fork
SOME WORDS OpenCore is fantastic and amazing bootloader(we wait for over 15 years) but inject ACPI and other things into Windows, Linux, etc and we need to use generic way(SSDTs) to boot into these Oses and avoid problems. With this OpenCore fork all these problems is solved and we can use one pe...
