Hello

Repair permissions & rebuild cache.

Done that, but nothing happended. I´ve installed applehda from here (as the first time i´ve installed osx):

Use KextWizard to install 2 kexts:
http://www.osx86.net/files/file/3832-alc283-applehda/​

My notebook audio is:

HDAUDIO\FUNC_01&VEN_10EC&DEV_0283&SUBSYS_102805FB&REV_1000

So i´ve installed alc283 driver (under notebook - realtek), but then again nothing happened.

ALC283 is the same as my Lenovo u430. You can use AppleHDA_ALC283.kext in my u430 repo...

https://github.com/RehabMan/Lenovo-U430-Touch-DSDT-Patch

Requirements:
- Clover bootloader
- config.plist must have the three AppleHDA patches from my config.plist in the repo
- AppleHDA.kext must be vanilla
- CodecCommander.kext installed to /S/L/E: https://github.com/RehabMan/EAPD-Codec-Commander
- AppleHDA_ALC283.kext installed to /S/L/E
- rebuild cache following the procedure detailed in the u430 guide: http://www.tonymacx86.com/yosemite-...ideapad-u330-u430-u530-using-clover-uefi.html
- DSDT patches "IRQ Fix" and "Audio Layout 12", with layout-id changed from 12 to 86.

Hi RehabMan !!

I've made a clean vanilla installation for OSX el Capitan. Following same steps I've patched same dsdt's, so i've achieved to enable intel 4400 QE/CI. But the problem is that the brightness slider control spite of it's activated, doesn't changes actual brightness of the screen. Do you know how can i fix this ?

I've couldn't copy patchmatic to /usr/bin, i've tried to disable SIP by booting OSX Recovery partition and using csrutil disable and restarted, but stills enabled.

Thanks in advance.

I followed this guide in order to have alc283 at el capitan, but nothing happened. It's curious because HDMI audio doesn't work either (it was functional using same guides in Yosemite). I couldn't get patchmatic copied to /usr/bin, but could you look at mi config plist / patched dsdt's ?.

Thanks in advance

You're injecting layout-id=12. My AppleHDA_ALC283.kext has never used layout-id 12, only 86 (old version) and now 3 (new version).

The instructions you have are old. Implement the same, but with layout-id=3.

I've repatched dsdt, added irq fix and layout-id=3 (from your repos) but no changes

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:

kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc

Also, post EFI/Clover folder.

I will do so, but i'm having troubles copying into /usr/bin (Write protected, spite of root user). I was reading it causes by SIP (new at el capitan). So I've booted up with rescue partition and disable it, but when i reboot it stills on.

Do you know how can i solve this?

Thanks

You need to disable SIP via config.plist.

My config.plist files from my guide have the needed settings: http://www.tonymacx86.com/el-capita...de-booting-os-x-installer-laptops-clover.html

And you should read here: http://www.tonymacx86.com/el-capita...-changes-workarounds-current-information.html

This probably explains your issues getting audio to work. You can't install unsigned kexts without SIP disabled.
