AppleHDA HDMI Audio [Guide]

[Rikoshet]

Hi Toleda!
Sorry for missing 2 questions! On HDMI I have a BENQ monitor, this monitor accept digital audio on HDMI and DP inputs, was working fine with gtx970, very usefull. Don't understand you second question "What port?". You mean what hdmi port on my GPU? If so, my GPU has only one hdmi output and my monitor also has only one hdmi port.
Like I told you in my first post I avoided black screen with Mieze dsdt patch. I was thinking maybe because of this patch I have no hdmi audio so I replaced this patch with more common solution: Lilu and WhateverGreen kexts. But no success, the only difference is now in System Information/Hardware/Graphics/Displays instead of "AMD R9 xxx" I have "Radeon Pro 580".

OK, i removed all native tables, now have only 3: DSDT, SSDT (XOSI) and your SSDT for audio.
Please take a look!
Thank you!

Don't understand you second question "What port?"

Translation, what port on monitor connected to what port on graphics card?
In your case: it is DP on both or HDMI on both?

removed all native tables

Not true, attached acpi tables:

Fix the acpi table problem.
Remove all Lilu and WhateverGreen kexts
Use the dsdt fix or the Clover fix, see Post #1/VII. AMD Radeon Graphics; not both
Restart, reply with all, new Problem Reporting files.

Hi Toleda!
Thank you for your patience!
From screenshots you'll see I'm using both connections, HDMI and DP, so I can quickly check the audio from both. I'm not using DP->HDMI adapters.
Now about tables: your screenshot doesn't reflect my situation. Please see attached screenshots of old tables from my post #159 and the last one attached. Anyway, in config.plist I dropped only 3 tables that give me problems. Should I drop all tables?
So, no more Lilu and WhateverGreen kexts, used Mieze dsdt patch.
May the problem be XFX vbios maybe?
Thank you!

IOReg shows one display, DP.

your screenshot doesn't reflect my situation

My mistake

Anyway, in config.plist I dropped only 3 tables that give me problems.

Attached config.plist does not match boot log, why?
config.plist/ACPI/SSDT/DropOem/YES means all, edit to NO
config.plist/ACPI/DSDT/Fixes/FixDisplay_0100/YES, edit to NO

no more Lilu and WhateverGreen kexts, used Mieze dsdt patch.

ssdt is not loading, dsdt patch

IOReg shows one display, DP.

Please, take a better look, there are 2 displays in ioreg. And in System Information/Hardware/Graphics/Displays.jpg you can find 2 displays. For now I unluged hdmi cable.

Attached config.plist does not match boot log, why?

Have no idea why, i have only this config.plist, no other to make a mistake.

config.plist/ACPI/SSDT/DropOem/YES means all, edit to NO
config.plist/ACPI/DSDT/Fixes/FixDisplay_0100/YES, edit to NO

Done, please take a look at new files.

ssdt is not loading, dsdt patch

Are you sure? Inside DPCImanager log.rtf I found this:
12:390 0:000 Inserting SSDT-HDMI-AMD-BR3A.aml from EFI\CLOVER\ACPI\patched ... Success

Now attaching new files.
Thank you again!

My mistake

Done

Agree

Are you sure?

Are you serious?
The dsdt patch changes H000 to PEGP, the ssdt looks for H000; ignored
Suggestion:
1. remove EFI/CLOVER/ACPI/patched/DSDT.aml
2. replace EFI/CLOVER/ACPI/patched/SSDT-HDMI-AMD-BR3A.aml with attached. The patch is added to the ssdt. dsdt is back to native, desirable.

 

[Rikoshet]

I can't use native dsdt because it was heavy edited to support xeon CPU! Without dsdt I can't boot! I need another suggestion!
Thank you!

 

[toleda]

need another suggestion!

Remove dsdt/PEGP and restore dsdt/H000
