VIA VT2021 and AppleHDA (as to be alternative)

VCH888 · June 1, 2012

After I had tested AppleHDA.kext on Gigabyte Z77M-D3H's VIA VT2021, I had found that a few ports could be working last two weeks.

This is the best I could make.

VIA_VT2021_for_Z77M-D3H.zip

requires AppleHDA from 10.7.4 update

If you are interested how to edit/patch AppleHDA, you can study from following information.

What do you need?

- codec dump from Linux

- Microsoft High Definition Audio Utility 3.3 (using Google)

- Xcode

Great. Will test it when i am @ home.

Hello,

i just tried to make my VT2021 work with AppleHDA using the Files that you provided but as it seems it doesnt work for me.

I followed your Guide/Readme.txt Step-By-Step and i am sure DSDT injection is working, but AppleHDA won't load for me.

So here is what the Console gives me:

The HDA-Device shows up in System Profiler, and even shows some Input and Output Ports.

But no Input or Output Device shows up in Audio/Sound Settings.

Since i already tried to make VIA VT2021 work with AppleHDA im am not suprised, because i know the Console Messages and behavior.

So when i just follow your Guide/Readme.txt HDA and Outputs show up in System Profiler but i can't use them.

When i add my own Verbs for Layout12 in AppleHDAHardwareConfigDriver.kext System freezes for about 2 Minutes after boot, i am able

to move my Cursor, but there is no reaction on Click or Keyboard-Input.

Console Output is something like this:

Jun  2 21:03:11 macintosh kernel[0]: IOHIDSystem: postEvent LLEventQueue overflow.
Jun  2 21:05:07 macintosh kernel[0]: IOHIDSystem: postEvent LLEventQueue overflow.

So i just want to find out if i am doing something wrong or i just missed a Step.

So here is what i tried Step for Step.

1. Edited my DSDT

	Device (HDEF)
	{
		Name (_ADR, 0x001B0000)
		OperationRegion (HDAR, PCI_Config, 0x4C, 0x10)
		Field (HDAR, WordAcc, NoLock, Preserve)
		{
			DCKA,   1,
					Offset (0x01),
			DCKM,   1,
				,   6,
			DCKS,   1,
					Offset (0x08),
				,   15,
			PMES,   1
		}
		Method (_PRW, 0, NotSerialized)
		{
			Return (Package (0x02)
			{
				0x0D,
				0x05
			})
		}
		Method (_DSM, 4, NotSerialized)
		{
			Store (Package (0x04)
				{
					"layout-id",
					Buffer (0x04)
					{
						0x0C, 0x00, 0x00, 0x00
					},
					"PinConfigurations",
					Buffer (Zero) {}
				}, Local0)
			DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
			Return (Local0)
		}
	}

I am sure that there is no mistake here, since Audio Device shows up in System Profiler with In- and Output Ports and AppleHDA gives me Messages on the Console.

2. Binary Patching.

I just entered the Command provided in your Readme.txt. Here is a point where i am not so sure what to do, i entered both commands without a big understanding

of whats happening here. Do i really need to run both commands? Or is it depending on something?

sudo perl -pi -e 's|\x84\x19\xd4\x11|\x41\x04\x06\x11|g' /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA
sudo perl -pi -e 's|\x83\x19\xd4\x11|\x00\x00\x00\x00|g' /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA

3. Copying the layout12.xml and Platform.xml to /System/Library/Extensions/AppleHDA.kext/Contents/Resources/

I am also sure that i made no mistake here, since it didnt work for me i also tried copying all layout*.xml files to this path but it still didn't work for me.

I guess when i just use Layout ID 12 in DSDT i just need to copy Layout12.xml + Platform.xml. Am i right?

4. I skipped the whole 10.8 DP3 Part since i am using 10.7.4

10.8 DP3 or later  Credits to revogirl for making perl script of zlib.pl
copy layout###.xml.zlib and Platform.xml.zlib to /System/Library/Extensions/AppleHDA.kext/Contents/Resources/
example;
sudo cp /where the file is/layout12.xml.zlib /System/Library/Extensions/AppleHDA.kext/Contents/Resources/

Terminal command: zlib.pl
perl zlib.pl inflate layout12.xml.zlib > layout12.xml
perl zlib.pl deflate layout12.xml > layout12.xml.zlib

5. I skipped the zlib.pl part since there was no layout12.xml.zlib provided in your ZIP-File.

6. Copied VIA2021.kext to /S/L/E and changed/fixed owner and permissions for VIA2021.kext and AppleHDA.kext

So here is the Question, do i need to add my Device/Codec ID to the Info.plist in VIA2021.kext? In my case the DeviceID is 0x1e208086.

7. Tried adding the Verbs you provided in VT2021-0 Document to Layout 12 in AppleHDAHardwareConfigDriver.kext but still no joy.

8. Tried adding the Verbs i use with VoodooHDA to AppleHDAHardwareConfigDriver.kext but System freezes for about 2-3 Minutes after Boot

and there is no reaction on mouseclick or keyboard input.

Maybe i just missed a Step somewhere, or at least i hope so, since i am really looking forward to using AppleHDA for my VT 2021

Thanks and Bye

Edit: As it seems i am using a different Mainboard, Gigabyte GA-Z77X-UD3H-WB WiFi but the Board also uses a VIA VT2020 / VT2021 Audio Chipset.

These sound assertions (four times) as I got related to trying to use nVidia HDMI audio and patched AppleHDA for VT2021 at the same time. I had no problem about these errors if I used AMD HD6870.

Sorry, I have no idea about overflow.

So here is the Question, do i need to add my Device/Codec ID to the Info.plist in VIA2021.kext? In my case the DeviceID is 0x1e208086.

You don't need to add this DeviceID.

I hope you copy Platforms.xml not Platform.xml.

I will continue to test my small board before I'll get a bigger one.

Hello again.

Okay, so now i have tried the patched AppleHDA.kext + VIA2021.kext and here are the Results:

I also added my PinConfigurations in DSDT and hoped this would change something, but no difference.

Layout ID 12:

Only Rear Green Output works and in Audio Preferences there is also the Digital Output, and for Input there is LineIn and Internal Microphone, but only the Green Rear Output works.

No Output on Black, Gray, Orange, Pink or Blue Rear, No Output on Green Front. No Input on any Port.

Layout ID 36:

Rear Green Line Out works and Front Green Line Out work (even when the Cable at Rear is still connected). None of the Other Ports work for Output or Input.

Layout ID 48:

Same behavior as Layout ID 12 but Input/Output Ports show up differently in Sound Preferences. So only Green Rear works, no Input or Output on any of the other Ports.

Here is the Pinconfiguration from my DSDT:

	Device (HDEF)
	{
		Name (_ADR, 0x001B0000)
		OperationRegion (HDAR, PCI_Config, 0x4C, 0x10)
		Field (HDAR, WordAcc, NoLock, Preserve)
		{
			DCKA,   1,
					Offset (0x01),
			DCKM,   1,
				,   6,
			DCKS,   1,
					Offset (0x08),
				,   15,
			PMES,   1
		}
		Method (_PRW, 0, NotSerialized)
		{
			Return (Package (0x02)
			{
				0x0D,
				0x05
			})
		}
		Method (_DSM, 4, NotSerialized)
		{
			Store (Package (0x04)
				{
					"layout-id",
					Unicode ("$"),
					"PinConfigurations",
					Buffer (0x34)
					{
						/* 0000 */	0x20, 0x10, 0x01, 0x01, 0x40, 0x60, 0x01, 0x01,
						/* 0008 */	0x50, 0x20, 0x01, 0x01, 0x60, 0x40, 0x21, 0x01,
						/* 0010 */	0x30, 0x90, 0xA1, 0x01, 0x70, 0x30, 0x81, 0x01,
						/* 0018 */	0x80, 0x90, 0xA1, 0x01, 0xF0, 0x00, 0x37, 0x50,
						/* 0020 */	0x90, 0x10, 0x45, 0x00, 0xA0, 0x10, 0x45, 0x00,
						/* 0028 */	0xB0, 0x10, 0x45, 0x40
					}
				}, Local0)
			DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
			Return (Local0)
		}
	}

But i dont think another PinConfiguration will change the Result since it doesnt make any differnce if i use it or not.

I also tried to add/change my verbs in AppleHDAHardwareConfigDriver.kext for LayoutID 12 and 36, but this didn't make any difference.

I dont know why the other Ports wont work for me, but i think the Result with Layout ID 36 isn't that bad

Thanks & Bye

EDIT: Maybe there is a Problem with the PinConfig, i am back to VoodooHDA at the Moment and i see all Ports (based on my verbs/Pin Config) in the

System Profiler. Maybe it will work out for me when i just customize the LayoutXXX.xml for my configuration and delete the obsolete "Pins" from Pin Configurations in DSDT?

Hello, i'm trying to patch AppleHDA (OSX Lion 10.7.4) for Via VT1708S.

I've read some documents, and tryied the patch myself.

1 - I bin patched Apple HDA

2 - I used DSDT-Patcher to fix my DSDT and add the audio part

3 - I edited the AppleHDAHardwareConfigDriver.kext plist to match my CodecID and my ConfigData (verbs dumped from linux and parsed with verbit).

4 - I edited layout12.xml to match my codecID and to remove

MuteGPIO

5 - I rebooted, and my soundcard was detected :-), but i didn't patch Platforms.xml, and so no input/output devices :-(

The problem is that i don't know what to do exactely with Platforms.xml. I have codec graph and codec verbs, but i don't know where to put which node.

Could someone could please help me?

I attach here some dumped files

Codec Dump.zip

eep357 · June 22, 2012

Since the orig poster is no longer working on this project, and no indication anyone ever got it fully working, I think voodoo is your best bet atm.

smx · June 22, 2012

Do you know where can i found some info about Platforms.xml? I googled a lot, but i figured out almost anything.

eep357 · June 22, 2012

well, for voodoo audio you would go here http://code.google.com/p/voodoohda/downloads/list and don't need to edit any xml files.

smx · June 23, 2012

Well, VoodooHDA already worked well for me, but i had some minor problems with the mic (echo effect) and wanted to try the HDA patch.

If there isn't any documentation on the new Lion HDA i will just wait and stick with VoodooHDA, thank you anyway.

lazybon3 · June 23, 2012

Hey smx,

maybe this solves your Problem with VoodooHDA:

Problem: audio feedback (Larsen effect), sound loop between input (microphone) and output (speakers).

Solution: mute iGain and increase iMix or Mic if microphone dosn't work

Code:

<key>iGain</key>

<string>0</string>

Source: VoodooHDA - common problems

If you want to "customize" your Version of VoodooHDA (cosmetic fixes, additional inputs and outputs) you should read the full post.

smx · June 23, 2012

Thank you very much you are a hero :-D The kext linked within the tread is PERFECT!

I finally managed to get the Prefpane to see my devices, and the igain trick (which failed on a previous kext), worked like a charm with this one

clickmikes · July 31, 2012

@lazybon3

Still got no Audio on my Z77M-D3H (VT2021), 3570K, Mountain Lion.

This is what I did:

1) Installed AppleHDA as per your instructions above.

2) Edited DSDT to add ID 12 to HDEF and added Method DTGP (found the instructions in another thread)

3) Installed VIA2021.kext (it does not show in kextstat)

4) Added 10.8 fixes (created zlibs and copied to AppleHDA.kext)

I can see Intel High Definition Audio Device in system profiler, and the details show Audio-ID: 12

However the speaker icon in my menu bar is greyed out and I cannot see any audio device in my audio settings.

Cannot add any audio device via Audi-MIDI-setup.app either.

Can you please give me some ideas where/how I can find a solution?

TIA

Michael

lazybon3 · August 2, 2012

@ clickmikes:

check out the other 2 posts about AppleHDA for VT2021 / VoodooHDA for VT2021.

I didn't find the time to take a look at it yet, i will install ML next week and post a solution asap. (i guess it will be by the end of next week).

i'm working on 1708s too. does the system can recognize the input/output devices in system profiler after your patch??

here is my work for 1708s platforms...

please try it.
