AppleHDA for Realtek ALC1220 - 10.12.3 - 278.56

I'm confused, how do I apply this? I've decompiled all my DSDT/SSDT files using ("iasl -da -dl *.aml" in Terminal), but when I copy the patch text into the Patch window in MaciASL I just get "2 Patches, 0 Changes, 0 Rejects".

This is because you have already applied this patch in your DSDT.aml then you just need to change the number of Layout_id that this being injected for 7

 

layout-id", Buffer() { 0x07, 0x00, 0x00, 0x00 },\n

Hm, weird. I've injected layout id 7 in Clover and installed the kext, but I still have no audio devices.

thanks for you feedback, let me know your specifications.

Here's my Clover folder (with aml files), IORegistryExplorer dump, DPCIManager bootlog:

I made a serious mistake and I'm going to fixed soon, by 
while the file this off.

Hi Mirone...

just some info... off "topic request"

could you provide more info about the codec id (0x10ec1220) and his correct name (ALC1220),

like "some" revision ID you find?

I would like to catch this infos to add it later in the varius bootloader and utility to get codec info...

--> http://www.insanelymac.com/forum/topic/285277-getcodecid-command-line-tool-to-detect-codec-id/?p=2361404

 

Example: the difference between ALC888(0x0888) and ALC1200(0x0888) is in the revision (ALC1200 has Revision Id: 0x100101)

 

Cordially

In IORegistryExplorer, I have revision-id <00 00 00 00>. My board is a GA-Z270X-UD5. Hope that helps.

 

The kext is also not working for me. If needed, I can provide a codec dump tomorrow.

Please send me a copy of your IOREG, after you have installed the kext.

Layout-ID has been injected with Clover

@Mirone

This may be a silly question but have you tried replacing either of the Skylake Sunrise Point device-id's in the AppleHDAController binary with the device-id of the Kaby Lake audio controller? The Sunrise Point audio controller device id's are a170 or 9d70, so in Clover you would do a find (70a1 or 709d) and replace (byte-swapped Kaby Lake id) kext patch...

Yes, But without any success, I'm trying

another path.

hey

with VoodooHDA 2.8.9 Works Fine do you need any Dump?

I have installed the VoodooHDA 2.8.9  on my gigabyte z270 gaming k3 and the sound works

VoodooHDA was already expected to work,

The point here is to make AppleHDA work.

@Mirone,

Happy to help with testing when my z270 arrives next week

@Mirone, I have been looking at the ALC1220 patch for the linux ALSA sound driver and it appears they are using the same patch as for ALC882.Does that help in any way?

Can you do some tests for me?

I had tried this before but it did not work.

I'll have a look at this, but I need testers.

@Mirone, This change is confirmed working on 200 series. Tested on Asus Prime Z270-P

 

AppleHDAController

Find 70a1

Replace f0a2

This works great, however not for HDMI audio.
