ALC268 trouble, is it possible to fix?

[TorAllex]

RoverBook Voyager V552 WH, ElCapitan 10.11.2, Clover
Most h/w working, except sound and native WiFi.
I've tried VoodooHDA - no voodoo devices detected. Also some patched AppleHDA.kext for ALC268, Clover injection with KextsToPatch - without any success.
Please, any suggestions (except "try Windows" and "move this scrap to trash", of course).

Ok, according [Guide] Patching LAPTOP DSDT/SSDTs ACPI extracted, disassembles, patched with audio_HDEF-layout3.txt and compiled.
Now, with patched AppleHDA (AppleHDA-272.50-ALC268 by Mirone), still have no sound

Ok, some piece of luck here.
With patched DSDT and AppleHDA.kext I have sound and mic now.
Please, help me - whats wrong? Why Intel HDA not present in a device list, why "built-in out"/"internal speaker" works trough 1/8-inch green jack only?

Read carefully. Make sure the layout-id matches your patched AppleHDA.

Also required: "IRQ Fix"

RehabMan, please look at my post #4

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.

Also, post EFI/Clover folder (press F4 at main Clover screen before collecting). Please eliminate 'themes' directory, especially if you have an overabundance of themes installed.

Using Clover DSDT fixes to an already patched DSDT is a bad idea. Do all patches manually, according to the guide: http://www.tonymacx86.com/el-capita...de-booting-os-x-installer-laptops-clover.html

According to ioreg, audio appears to be working...

Now boot without Clover DSDT fixes - same result
