El Capitan: Realtek ALC AppleHDA Audio

llamafilm · September 18, 2016

That's what I was doing. But never mind, because I now have it working with AppleALC instead. I just need to figure out how to get HDMI audio now.

mrjayviper · October 1, 2016

is the 120 script the only option when using Sierra? thank you so much!

mrjayviper · October 1, 2016

So I got sound working on my setup (ALC888) using the 120 script. Looking at the 120 script log (see below), is it possible to save:

EFI/CLOVER/kexts/others/realtekALC.kext
S/L/E/AppleHDA.kext
EFI/CLOVER/config.plist (seems the 120 script made 3 changes to AppleHDA via Kernel/Kext patches - see below)
Any others files/config I need to save?

so I don't have to run the script all the time I reinstall Sierra?

Another question please: What happens if I got an OS X update? Do I need to rerun the script?

Thank you so much!

Can I get some assistance please? I've spent hours to no avail.

- Fresh install of Sierra on a Acer Aspire Desktop PC

- Clover EFI Legacy boot

- No DSDT or SSDT , all stock kexts

- Used CloverALC120

- Codec is Realtek ALC888S-VD 0x80863A3E Sub-Device 0x10250152 Codec ID 0x10EC0888 Revision 0x0202

AppleHDA.kext in use and ioregistry are attached.

Result is no audio device detected except an input mic device for the Logitech camera. ALC888 not detected at all and does not appear in Sound preference pane.

toleda · October 5, 2016

so I don't have to run the script all the time I reinstall Sierra?

What happens if I got an OS X update? Do I need to rerun the script?

Installs do not effect EFI/CLOVER files. Backups do not offer any advantage. Run the script once for a new install.

No, updates do not touch the installed codec files.

Result is no audio device detected

No pinconfigs.

Copy EFI/CLOVER/kexts/Other/realtekALC.kext to 10.12

Before that, I installed VoodooHDA kext, it worked but after shutting the static noise in the pref pane, I still had an annoying ticking noise, so I uninstalled it completely then put back the native AppleHDA.kext from a clone disk.

Hope this helps you to help me :-)

trying to install ALC AppleHDA without success,

No audio codec is a hardware problem, neither Clover or OS X see the codec.

When the codec shows in DPCIManager, the script runs to install audio.

jeanba3000 · October 14, 2016

OK but why voodooHDA works (except the noise problem) ?

jeanba3000 · October 14, 2016

Well, after a search on google, I found this guide on Reddit that led me to AppleALC.kext, I put it in my kext/others folder, restarted, and it's working.

Mondstaub · October 26, 2016

Problem Description:

I have static, crackling noise. It's low in volume and is ocurring when moving the mouse, using keyboard be it bluetooth or wired. It also occurs when loading a App. It's also audible when i listen to headphones out on the front of the case or the one direct from the MOBO, the same is when i use USB Soundcard Apogee Duet2. It gets not louder when i increase the volume, it stays at the same loudness.

OSX Version: El Capitan 10.11.6 / i Mac 17.1

MoBo: Gigabyte Z170X-UD5 TH/BIOS Ver: F5

Proc: i7 6700K

GFX: EVAGA Geforce GTX 950Sc

Mem:Crucial Ballistix Sport LT 2x16GB

I have ALC1150 and the 100 Series Audio installed i also ran AppleHDAEnabler using Kext Utility. In order to get the Nvidia Drivers to work i had to disable SIP first and then run two AGDP patches. As System Spec i used iMac17.1 and i also increased the USB Portlimits.

I tried to fix the issue with below codelines injected into my plist, it did not help. First i wrote only USEARTFrequency and false and a second time the lines below.

I also disabled the LED on the MoBo in BIOS wich makes the LED flash to the beat on the MoBo, just fancy stuff i dont need anyways and i thought/hoped that it might have caused this problem.

<key>CPU</key><dict>    <key>QPI</key>    <integer>100</integer>    <key>UseARTFrequency</key>    <false/></dict>

As i'm new to OSx86 project i hope i did post my problem as it should be and ask you to bear with me and my non to little existing experience. Thanx

Update:

I finally found the culprit as i went thru all BIOS Settings and tested different settings. On the Chipset Menu i disabled internal GFX and since then the problem is gone. I booted now about a dozen times just to be shure and it looks to be fine.

Now fingers crossed i start to install DAW, plugs and look how the midi stuff works out. If midi over wifi works i'm a happy camper. :yes:

Post #1 is updated for 10.12.

Have to check with a mod to see if I can simply rename the thread.

Hello, I have a dell optiplex 790, i3 2125 and using IGPU hd3000, I installed mac os Sierra and most things seem to be working fine but no audio, audio chip is ALC269VB, I followed the guide here https://github.com/toleda/audio_CloverALC , I have SSDT-HDEF-1.aml and DSDT-HDMI-HD3000.aml patches in my clover acpi folder, I ran the script audio_cloverALC-120.sh and was successfully completed. I have still no audio. I really need help to get this working, thanks!!

audio chip is ALC269VB

See Post #1(supported codecs):

Realtek Codecs and Applications

ALC269/0x10ec0269/BRIX

Apologies, cloverALC only supports BRIX/269.

KEVINMAC · December 6, 2016

Yes, sorry for posting, I thought It was gonna work since the device-id and vendor-id are the same. Thanks.

woutetjee · December 21, 2016

Hello Toleda,

I used this method to patch my audio, it works now!

Well, only the ports on the motherboard worked...

So I was figuring what could be the problem, then I found out my good ol' computercase has the so called "AC'97" plug instead of the "HD_AUDIO" one.

So there was no detection of the front audio, as an electrician this made me think there should be a "mechanical" solution.

I started to search for google pictures and found out if you shorten the right contacts on the audio header, the software will think there is a cable plugged in...

So I started searching in my computer parts bin and found a jumper wire that fits in the plug.

And it turns out it works!

Just wanted to share this with you, so if someone asks if it's possible to make the front audio working, you could give this as a solution.

If you shorten pins 7 and 10, the headphone port is detected, if you shorten pin 6 with pin 7 as well, the microphone should work to.

Hope this can help you in the future.

toleda · December 21, 2016

thought It was gonna work since the device-id and vendor-id are the same.

The OEM configures the codec to specific product requirements with custom layouts, pathmaps and pin configurations. The codec is the same, the configuration is specific to the motherboard.

searching in my computer parts bin and found a jumper wire that fits in the plug.

And it turns out it works!

The jumper disables/mutes the green port on the motherboard, same with pink if jumper installed.

The software solution is to separate the front panel jack from the motherboard jack with a pathmap edit, see Post #1/More Information/2. Customization

stongpa · January 16, 2017

I am seeing a strange behavior with my audio, I have a RealTek ALC 887, the audio works perfectly after I apply the toleda's cloverALC_120 script, but after several reboots the audio will stop working (No Output devices found), then I have to replace the AppleHDA.kext with the native one and redo the patch.

I am not sure if it has anything to do with the external usb drive or disks.

Can someone help?

My setting:

Inter Core i7

20GB 1333 MHz DDR3

ATI Radeon HD 5000 1024MB

I followed toleda's instructions:

Using Clover configurator, before I run the script, I did the following

ACPI/DSDT/Fixes/NO all unchecked
Set RtVariables/BooterConfig/0x28
Set RtVariables/CsrActiveConfig/0x3

Run the script, verify the AppleHDA.kext has version: 274.12-toledaALC887

Then remove the BooterConfig and CsrActiveConfig values in Clover.

audio_realtekALC-120_v1.0d.command Output Success.txt

audio_codecdetect v2.1 Output.txt

toleda · January 16, 2017

Then remove the BooterConfig and CsrActiveConfig values in Clover.

Why?

Why is HDAEnabler1.kext installed?

Only when no audio devices show. See Problem Reporting, Post #1; attach all requested files

No need to post on my threads in multiple forums.

UNOE · January 25, 2017

I'm having a issue were when I reboot it always changes to Headphone out instead of Optical. I only use optical and want it to stay on optical on every boot. This issue was not present through Yosemite and El Capitan and Sierra for years. Now its a issue. I think it happen when I had connected a DAC that I returned. I think it tries to use that DAC then can't find it goes to headphone as default. I don't know if that is the case really though.

But is there a way to reset the default device on boot?

toleda · January 26, 2017

is there a way to reset the default device on boot?

Never encountered the problem. Not aware of any solutions.

llamafilm · January 26, 2017

But is there a way to reset the default device on boot?

You can write a launch daemon to change the output device using this command-line tool. Not sure if it works on Sierra, but give it a try: https://github.com/deweller/switchaudio-osx

El Capitan: Realtek ALC AppleHDA Audio
