AppleHDA HDMI Audio [Guide]

[chumdoggin]

No HDMI connector, no HDMI audio. AMD does not support audio on the DVI connector, Nvidia does.

On osx correct? I see that windows 10 broke the multichannel and people were trying to use the older drivers and having problems. So there must be quite of bit of extra code thats not worth the trouble for them on such an old card? Let alone apple

Your card has an HDMI audio codec. It does not have a HDMI port or a DP port. No AMD4800Controller framebuffer supports DVI audio.

Script: HD4600+ HDMI audio is enabled
Missed: Post #1/II. cloverHDMI/6. Notes/3. Attempted HDMI audio ...
Script will not work until all previous methods are removed.

of course, but the HDMI still does not appear

only appear when set clover config inject audio 3 but also I am in the same of not knowing what framebuffer to use or if I have to touch another thing of ssdt or of the clover config (that I am using the rehabman config to 4600 https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/config_HD4600_4400_4200.plist )

now I just see that it says that this configuration is for laptop and I am configuring a desktop, I do not know if it can influence that the HDMI does not appear correctly

Post #1: "Attempted HDMI audio and not working; remove all previous attempts"
To be clear, remove all previous HDMI audio methods.
This thread only supports Post #1 HDMI audio methods.

yes, removed all old audio methods

now with vanilla audio kexts and vanilla rehabman 4600 clover config (with audio inject 0) don't show HDMI or other sound

which audio inject is the correct for 4600 with 9 chipset intel ?

in the audio script appear
EFI partition is mounted
No HDMI audio codec(s) detected, continue (y/n):

Hello Toleda!
Thank you for your hard work.
Unfortunate I have a problem and I’ll try to describe as by Problem Reporting.
1. So I swapped my gtx970 for rx580 8g and make it worked (usual black screen problem) with this patch:

http://www.insanelymac.com/forum/topic/328549-tracing-back-the-amd-gpu-wakeup-issue-to-its-origin/

I deleted SSDT I used with Nvidia card and using audio_cloverHDMI-130_v0.6.command installed new SSDT, reboot and nothing.

2. I’m on 10.13.1/ga-x99m gaming 5/Bios F22/xeon e3-2695 v3/XFX rx 580 8gb

3. Procedure/Guide Used audio_cloverHDMI-130_v0.6.command

I see you are talking about AMD9520Controller/AMD9510Controller/AMD9000Controller/AMD8000Controller kexts, but from my ioreg I see in my case I have AMD9500Controller.kext. May this be a problem?
Thank you!

reboot and nothing

"Nothing" is far from true; SSDT-HDMI-AMD-BR3A.aml is installed and working.
What HDMI device is connected? What port?
Why are a bunch of native ssdts copied to EFI/CLOVER/ACPI/patched?
There is a copy of SSDT-HDMI-AMD-BR3A.aml named SSDT-2.aml, remove

 

[Rikoshet]

Thank you Toleda!
By nothing I mean no audio.
Native ssdts are there because a couple of years ago i have had some problems, droped native ssdts by Clover and have to injecting back one by one..don't remember why, but it works and worked with nvidia audio.
I removed SSDT-2.aml.
What you think?
Thank you!

 

[toleda]

What you think?

Post #156: Ignored the first two questions, reply with answers
Why did you install both versions of Lilu and WhateverGreen?
FACS.aml is loaded 3 times
Remove all native ssdts from EFI/CLOVER/ACPI/patched
Restart, reply with new files
