Keyboard (No backlight)
Full native HD Display with touch
Networking (Ethernet)

USB 2.0/3.0



A guide will be compiled upon successful utility of all features



I am unable to get the sound working. I have scoured the Internet trying to make sense of AppleHDA patching but it does not appear that I have the correct codec to apply those techniques. I've posted my Linux extracted DDST/SSDT, ioreg output and codec_dump here if anyone can provide some assistance or guidance.

Thanks in advance!

Codec dump is for the wrong codec. Look on Linux for codec dump for onboard graphics, not Intel HDMI.

Apologies, the correct file has been attached.

I have tried to apply what I read therein but have so far been unsuccessful. At this point I'm not even sure if my codec is compatible with these guides.

I've:

-Extracted codec and relevant information
-Extracted verb data

The part where my confusion begins is correcting the verb data. Any suggestions would be helpful..

Try using AppleHDA for ALC283 (note: 0x10ec0283 in codec dump).

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.

I appreciate your prompt support and will try your suggestions later today. I would however like to learn as well. Now I know that the line that literally reads "Codec" isn't the actual codec name.

The next matter of difficulty was application of verb correction.. Do you know of any resources that more clearly addresses how it is done in the codec and why perhaps e.g. "every-time you see a "9" replace with a "0" because.."


Your assistance as always is appreciated!


Edit: I tried the suggestions you made, but the device does not appear in "About This Mac" and my sound icon remains unavailable.

I loaded the kexts as instructed and made the necessary config.plist and DDST changes. Any ideas?
I've attached the two files I attempted to change.

To understand that, you'll need to read the Intel HDA spec (approx. 700 pages).

Thank you for the resource, I'll look through it. This is the output from the grep functions:

AppleHDA.kext is not loaded. Probably due to:
- layout-id is not injected via DSDT patch
- AppleHDA may not be vanilla

I've repatched the DSDT and compiled without error, and copied an APPLEHDA.kext from my iMac running Yosemite.

Rebuilt cache as per your directions but on reboot there is still no sound.
