Sebinouse's Build : CustoMacMini 2014 - Intel NUC Haswell i5-4250U - El Capitan

[Sebinouse]

When you make an analysis of the ALC283 variants in another excellently crafted AppleALC.kext and Lilu.kext, info.plist, platform.xml and layout.xml, you will find that if it accidentally produces sound - even disastrous, including downtime, it's just a happy match coincidences.
The most recent ApleALC.kext in its pinconfig has three versions for ALC283, only the Mirone version is closest to my version.
Here's the detail of the comparison.

My NUC Broadwell 5i5 RYB

Final changes in pinconfig
PinConfigurator output + EAPD for input and output
01971c00 01971d10 01971e81 01971f01 01470C02 02170C02
02171c10 02171d10 02171e21 02171f01 01470C02 02170C02

I've been struggling for a looong time with our ALC 283 ... especially to get hot plug support and prevent codec sleep ...

you can have look to my studies here

I don't have enough to time to look to this again but if you want to add EAPD support to Input 019 and Output 021 you should add only one time 70C02, which gives you :

PinConfigurator output + EAPD for input and output
01971c00 01971d10 01971e81 01971f01 01970C02
02171c10 02171d10 02171e21 02171f01 02170C02

I do not know as much as possible, but your EAPD combination only plays one channel after the start. Honorable, my EAPD combination is playful. Thank you very much for your interest and your great in-trainings at MacBidouille Forums.
Comic is that audio output works from El Capitan to Sierra High Beta 1 and 2. AppleHDA patcher will boldly set up a binary patch and it's done.

That a very good news ... Does your MIC work also ? and finally can you share your dummy HDA kext (or your Zlib + plist files) ?
Thx

MIC unfortunately does not work. I desperately wanted to completely cancel both Input and MIC, but the key is probably EAPD in Input. I'll still experiment with the MIC.
Even under Windows 10, the MIC has begun to work right after the latest Realtek driver for Intel.
Certainly this is not a definitive solution and applies only to Broadwell NUC 5i5 RYB - Revision Id: 1048579
In El Capitan works full patched AppleHDA.kext or aDummyHDA.kext, Sierra High Beta only full patched AppleHDA.kext.
Binarypatch in Sierra High may not be entirely correct

Finally, the solution for ALC 283 is Toleda cloverALC 130
