Experimental 6 channel AppleHDA

[shiecldk]

This patch method will get analog surround sound work in AppleHDA's native multi-channel output rule. If you have problem with this, please use traditional way to patch your AppleHDA.

 

Credit to: THe KiNG, bcc9, Revogirl, TimeWalker, 紫米, VCH888, EMlyDinEsH and many others.

 

If you've never patched AppleHDA, I recommend you to read these two guides about patching AppleHDA before reading this topic. 

The KiNG's Guide

EMlyDinEsH's Guide

 

Take my ALC889 as example:

1. Center Speaker and Subwoofer

2. Left and Right Surround

3. Left and Right Rear (used for 7.1 surround sound)

4. Line in

5. Left and Right Front

6. Mic

7. S/PDIF Optical and Coaxial

 

Internal Speakers: 5 + 1 + 2

Line Out: 3

Digital Out: 7

 

Internal microphone: 6

Line In: 4

 

No longer need to setup aggregate device in Audio MIDI Setup to get 6 channel output!

6 channel sound is confirm worked on Built-in Output, even though it's showed as 2 channel in Audio MIDI Setup. (same as Built-in Digital Output)

There is no way to adjust the volume in each channel under OS X. You have to adjust the volume on your speakers.

Be careful about the Internal Speakers:

We need to setup "Sequence" (0, 1 & 2) for the analogy multi-channel jacks and use the same "Default Association" to group them.

I also changed the jack color to unknown (0), as Mac always use 0 for speakers in PinConfigurations. But I don't think it's necessary.

And change all "Default Device" to speakers (1).

40 01 10 90
42 01 10 90
41 01 10 90

 

Let's take MacBookPro5,2's  PinConfigurations as reference:

50 40 2b 01
20 30 8b 01
41 01 10 90 // 6ch speaker
42 01 10 90 // 6ch speaker
10 01 a0 90
40 01 10 90 // 6ch speaker
70 90 a1 01
60 e0 4b 01
30 e0 cb 01

"Use ambient noise reduction" is available for Internal microphone (rear mic) in System Preferences after changing "50 9c a1 01" to "10 91 a0 90".

 

Layout

Outputs:

 

Headphone:

I've tried to put AmpPostDelay and AmpPreDelay=100 under both Headphone and IntSpeaker. But I found out there are some instrumental sound being cut down in musics and human voice become a bit lower?! I'm not sure.

 

IntSpeaker:

It's necessary to setup this SignalProcessing under IntSpeaker, otherwise sound will be distorted even you are not using 6 channel output.

There is a value "Dsp6ChOutput" in SignalProcessing. As the name implies, it's used for 6 channel. This is a key to enable AppleHDA's native 6 channel DSP support. Even if you have a different sound card other than my ALC889, you should still use this SignalProcessing section inside the layout.xml, which I attached in ALC889 xml.zip at the bottom of this post, for your IntSpeaker.

This whole SignalProcessing section was discovered by VCH888. Thanks to him!

But unfortunately, there is no Dsp8ChOutput in AppleHDA, as I've checked all layout xml files and AppleHDA's binary. It's not possible to setup 8 channel sound this way, as AppleHDA does not have 8 channel DSP support.

 

LineOut:

 

SPDIFOut:

The signal is digital, so no need to setup any value right here.

 

Inputs:

 

LineIn:

There are some problems for hackintosh to use ExtMic. So I changed the rear and front mic to internal mic and line in.

MuteGPIO: 0x50 (VREF_80) + 0100 + NodeID (19) = 0x50010019 = 1342242841

 

Mic:

MuteGPIO: 0x50 (VREF_80) + 0100 + NodeID (18) = 0x50010018 = 1342242840

SignalProcessing is used for reducing noise.

 

 

Platforms

The easiest part for sure if you patch AppleHDA in normal way, but using AppleHDA's multi-channel output rules is another case.

 

0

-0    //Mic (rear mic)

--0

-1   //LineIn (front mic)

--0

1

-0    //LineIn

--0

2

-0    //IntSpeaker (We have to be careful about this in PathMaps. Notice that the jacks are in the same group.)

--0    * Black Jack - Left and Right Surround

--1    * Orange Jack - Center Speaker and Subwoofer

--2    * Green Jack - Left and Right Front

-1   //Headphone

--0

3

-0   //LineOut

--0

4

-0   //SPDIFOut

--0

 

Let's talk about IntSpeaker:

All Amp values must be same as what the pictures show below.

(2, 0, 0) Black Jack - Left and Right Surround

(2, 0, 1) Orange Jack - Center Speaker and Subwoofer

(2, 0, 2) Green Jack - Left and Right Front

 

When it comes to mic:

The higher Boost value (0~3) you setup, the more sensitive mic you get.

 

Result:

Analog 6 channel surround sound can be output by selecting "Internal Speakers" in System Preferences!

And no more useless LineOut devices in System Preferences now.

        } 

 

 

 

 

**Cautions for OS X Yosemite**

There are some changes needed to be made after updating to OS X Yosemite.

 

Firstly, this Boot Argument is necessary to be added in order to load the patched AppleHDA correctly:

kext-dev-mode=1 

Secondly, Binary Patch had also changed:

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

sudo perl -pi -e 's|\x8b\x19\xd4\x11|\x89\x08\xec\x10|g' /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA  

Good luck! And please do not copy my guide to other website, especially Tonymac's forum!  (But I guess they won't even understand this.  )

Work fine on my system... (Gigabyte board)

Are you using the latest AppleACPIPlatform.kext (2.0)? It seems some people, who are using the older AppleACPIPlatform.kext, have problem with 10.9.2's AppleHDA.

Hi:

I followed your guide for ALC892, but I couldn't make it to work (10.9.2) 

Using DSDT with Layout 1

I am experiencing a hybrid between a guide and a AppleHda.kext of Toleda (which works when it wants to) 

I'll try changing AppleACPIPlatform.kext and see what happens. 

Thank you.

 

 

P.S.:

Are you using the right binary patch for ALC892?

According to bcc9's topic, it should be this one in your case:

sudo perl -pi -e 's|\x8b\x19\xd4\x11|\x92\x08\xec\x10|g' /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA 

I'd recommend you to make your own AppleHDA staring from the vanilla one.

Try to understand the guide from THe KiNG -> EMlyDinEsH -> and finally this topic.

If you've already known how to setup PinConfigurations' value, you can skip to EMlyDinEsH's guide. (It will take you a little time to understand how to patch AppleHDA. Good luck! )

I can't make dsdt with

I am also having this issue.  Any way to resolve?

[carbo178]

@manor and og-phantom:

Yes, same issue in dsdt, but audio works well.

Check if layout is 32 in System Profiler

[shiecldk]

@manor, og-phantom and carbo178 (lol There's too many of them...)

I use MaciASL to edit my DSDT.

It will convert "0x20, 0x00, 0x00, 0x00" to unicode automatically, so that you won't have to be worry about it. 

[carbo178]

Yes, is all OK, my sound works well and layout-id is 32

I use DSDT Editor and it convert exadecimal in unicode same as maciasl

 

Sorry for my english

[Rodion2010]

Thanks for the Guide!

Can You or anyone else describe more exactly what to do with AMP values?

All Amp values must be same as what the pictures show below.

(2, 0, 0) Black Jack - Left and Right Surround

(2, 0, 1) Orange Jack - Center Speaker and Subwoofer

(2, 0, 2) Green Jack - Left and Right Front

<key>Channels</key>

<integer>3</integer>

</dict>

<dict>

<key>Bind</key>

<integer>2</integer>

<key>Channel</key>

<integer>4</integer>

</dict>

 

I think 1 and 2 is Front, 3 and 4 - Center/LFE , 5 and 6 - Surround. Is it OK for any Codec and where did these values come from?

and another question, if path contains two AMPs

How do I need to modify Channels and Bind? The First One, the Second or Both?

[Rodion2010]

finally I made Platforms.xml for my codec, AD1988b and it works, but sound is distorted (( I have problems with DSP Section and need some help.

Thanks

5.1ch_ALC898.zip

 

This folder is a sample of 5.1ch_ALC898.  I made two layouts and SoftwareDSP was based on layout70.  They are almost the same except “ParameterInfo of DspFunction2, 3, and 4.”   I have no idea how to edit or modify “ParameterInfo” and hope that someone can make it better, especially ParameterInfo.

 

Note: 

1) I had to swap channel of orange jack to get sound on Center speaker. (using an additional 3.5 mm jack male to female cable and swapping audio cable)

2) The sound from layout1, w/ ParameterInfo, is better than layout2, w/o ParameterInfo.
