Not a guide. Moved to laptop support.

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 four AppleHDA patches from my config.plist in the repo (but not the zml.zlib patch)
- 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 3".

Thanks for more info, can i ask you, what does "- AppleHDA.kext must be vanilla" means?)

Meaning AppleHDA.kext should be exactly as provided by Apple, no patches.

Thanks, now this clear, but still got a questions
About: DSDT patches "IRQ Fix" and "Audio Layout 3".
Ok, I find this fixes in your repo, what should I do with them?
I should launch clover, press F4, will get a dsdt file, then I need to follow the guide to dissassemble it or something like this and apply this to my dsdt, right?)

Hey, Rehab, i've followed the guide, but i am stocked and don't know what to do next. I have downloaded aisl, moved it to usr/bin, installed app, disassembled dsdt and ssdt's with the terminal + refs.txt, but i'm still got errors in ma dsl files, and i still don't understand, what should i do with the patches files (irq fix.txt, for example). Could you please help me?)
This is how my origin+disassembled files look like. And i have bad feelings about this in my dsdt.dsl:
/*
* iASL Warning: There were 27 external control methods found during
* disassembly, but only 18 were resolved (9 unresolved). Additional
* ACPI tables may be required to properly disassemble the code. This
* resulting disassembler output file may not compile because the
* disassembler did not know how many arguments to assign to the
* unresolved methods. Note: SSDTs can be dynamically loaded at
* runtime and may or may not be available via the host OS.
*
* In addition, the -fe option can be used to specify a file containing
* control method external declarations with the associated method
* argument counts. Each line of the file must be of the form:
* External (<method pathname>, MethodObj, <argument count>)
* Invocation:
* iasl -fe refs.txt -d dsdt.aml
*
* The following methods were unresolved and many not compile properly
* because the disassembler had to guess at the number of arguments
* required for each:
*/
/*
* External declarations were imported from
* a reference file -- refs.txt
*/

If i do this in my original mac, i get this:

This appears after audio 3 fix patching
Added the dsdt.dsl from my hackintosh, but decompiled in original mac.

You're using the wrong version of MacIASL here. Or you didn't set ACPI 6.1 in MaciASL->Preferences.
Only one error in the file you attached.
Your mistake... you forgot to apply "Rename _DSM methods to XDSM" or "Remove _DSM methods" before applying other patches.
The _DSM issue is very clear in the guide, as is correct version of MaciASL and MaciASL ACPI settings.
You should read it carefully.
