But It still have not HDMI audio.

Why config,plist/Devices/Properties/PciRoot(0x0)/Pci(0x1f,0x3)/alc-layout-id/<05000000>? Remove
No Intel HDMI audio codec available, enable in BIOS
Restart, reply with new files

Hi,

I add "alc-layout-id" because I have just noticed that without this properties, I haven't any sound present into macos System if i didn't add this option.

Do you mind that there is an option into my bios that I have to modify ? I have tried you find into my bios option if I could see some options link to HDMI but I didn't see anything. Maybe I don't understand all options present into my bios



But It strange that if I unplug than plug my HDMI screen after booting ... I could get the HDMI audio...


Before unplug/plug screen:
==================
MiniMac:~ jpc$ ioreg -rxn IOHDACodecDevice | grep VendorID
| "IOHDACodecVendorID" = 0x10ec0892



After unplug/plug screen:
==================
MiniMac:~ jpc$ ioreg -rxn IOHDACodecDevice | grep VendorID
| "IOHDACodecVendorID" = 0x10ec0892
| "IOHDACodecVendorID" = 0xffffffff8086280b


Best regards

Internal AppleALC.kext property, usually 7. 2nd request, remove.
To figure out why layout-id does not work, attach all files.

Not strange, something is not set properly
Attach both IORegs.

Hi,

I have just removed "alc-layout-id" from config.plist and reboot. I haven't any sound.

I haven't any sound

Intel HDMI codec has disappeared, enabled?
framebuffer-con1-type=<00080000>, not working?
Download latest AppleALC.kext and Lilu.kext and install
Restart and reply with new files

Hi,

Thanks again for your support. How I could control that "Intel HDMI codec is enabled"? I didn't touch any thing on Bios configuration..May I have ?
How I could check if "framebuffer-con1-type=<00080000>" is working ? Because all seems good on my graphic display...

I have just dowloaded and installed the last version of AppleALC & Lilu into EFI/CLOVER/kexts/Other to replace the old version... but after rebooting I still have not sound...

Best regards.

How I could control that "Intel HDMI codec is enabled"?

BIOS setting (i.e., Maximus VII Impact: Advanced/System Agent Configuration/CPU Display Audio/Enabled)

How I could check if "framebuffer-con1-type=<00080000>" is working ?

IOReg:

I have the 7500u version of this device. I had to patch my DSDT to and add audio. This device is basically a laptop motherboard stuck inside a small aluminum chassis. It is an alc892 board. Use Headkaze's "Hackintool" to add layout id 4 to your clover plist. I'll attach mine for reference.

Config worked great on same machine (Hystou 7500U). Both video ports (had trouble using Hackintool to get those working), sleep, wake, shutdown. Thanks!
