Audio - Realtek ALC AppleHDA [Guide]

optical audio is currently working great in stereo. I am attempting to now enable 5.1 output via the optical.

So, Toleda, for an X99 board (Asus and 5820k) with the ALC1150 audio chipset, would the following work in your view? I thought I’d summarize the steps I think should work to see if I got it right (note, I'm trying for a Clover only solution so that I don't have to worry about updates):

Step One: Clover config.plist editing

Basically create a key in config.plist (I would use TextWrangler, probably)
Edit the Inject key under Devices/Audio in config.plist….

<key>Devices</key>
<dict>
<key>Audio</key>
<dict>
<key>Inject</key>
<integer>1</integer>
</dict>
</dict>>

Step Two: And this is where I get confused:

Add a new key under KernelAndKextPatches/KextsToPatch in config.plist. Using the Base64 encoded versions of the patches (because I'm using a Text Editor), patch appropriately (which for me is an ALC1150).

So, here’s my guess as to what the key should look like:

<key>KernelAndKextPatches</key>
<dict>
<key>KextsToPatch</key>
<array>
<dict>
<key>Comment</key>
<string>Realtek ALC 1150 Patch</string> <—???Mine is an ALC1150>
<key>Find</key>
<data>AAnsEA==</data> <—??? editing via text editor, for the ALC1150>
<key>Name</key>
<string>AppleHDA</string>
<key>Replace</key>
<data>mQjsEA==</data>
</dict>
<dict>
<key>Comment</key>
<string>Realtek ALC Codec Patch</string>
<key>Find</key>
<data>gxnUEQ==</data>
<key>Name</key>
<string>AppleHDA</string>
<key>Replace</key>
<data>AAAAAA==</data>
</dict>
</array>
</dict>


Step Three: Run these commands as root:

curl -o ~/AppleHDA8Series.sh https://raw.githubusercontent.com/Piker-Alpha/AppleHDA8Series.sh/master/AppleHDA8Series.sh
chmod +x ~/AppleHDA8Series.sh

Move newly created kext to /Library/Extensions.

Sorry to ask, but did I get this right?

And thank you! for all the work you do supporting the rest of us!
 
did I get this right?
No.
See Post #1Unsupported/Non-working Realtek ALC AppleHDA
2.X99/Intel High Definition Audio

do not use a text editor for plists, download Xcode

See Post #1
III. Piker-Alpha AppleHDA8series Script (10.10 working, 10.11TBA ...)

select a different method

Well, at least you can say I tried. Thanks for the very quick response!

And, I tried again! This time I succeeded....

Step One: I used Audio_ID Injection Method 1
  1. Clover Injection
The trick here is to use Plist Editor Pro to copy the plist sub-clause from the download (config-audio_cloverALC-x99.plist.zip) to your exiting plist (and put it in the right place!).

[FONT=inherit !important][FONT=inherit !important]Restart[/FONT][/FONT]

Step Two: I used IOReg Explorer, GUI version to verify the below, which verified correctly.

  1. Verify IOReg/HDEF/layout-id/<01 00 00 00>
Step Three: Again another plist cut and paste:config-audio_cloverALC-x99.plist.zip

  • Add config.plist/KernelAndKextPatches/KextsToPatch/10.9.4-10.10-/x99 ALC Onboard Audio
Step Four:
Step Five:

  • Restart and test - and for me, with my system, it worked.
 
Hi, i have replied your post because i have no idea how to create my post.. please help me with my audio codec issue.. i recently switched to mac on my hp probook 4530s.. i have never used mac before, so i have no idea how to modify system root files like the plist.. i tried so many methods mention in post #1.. but no success..
i have tried audio_cloverALC-110_v1.0o10.command.. i get unsupported codec on start and it says some ssdt kerneltopatch are missing.. and no success.
i have also tried audio_realtekALC-110_v1.0o1.command.. unsupported codec.. and asks me to select codec.. i choose 885 and different types.. restarts and no success.
the i use the audio_codecdetect.command.. i get File: audio_codecdetect.command_v1.2

HDMI audio codec(s)
Intel: 0x80862805

Onboard audio codec

Thanks in advance
 
What alternative is there for ALC889A? The ALC889 in MB results in no audio devices found. Is this a dead ALC codec and is voodoo my only alternative for this GA-EP45-UD3P so far as El Capitan is concerned?
I suspect I have some DSDT patching to do on this one. No big deal, need to do it anyway to get rid of NullCPUPM kext. Will be working on that this week if I have time.

The 889A is Gigabyte's marketing name for the 885, OS X native. 889 is a different codec.
