Great ! layout 13 and 56 work fine! Now, sound work (but may be just a little low, i don't remember for compare), and mic working to (Siri heared me!)

But headphones - not :) Sound are switched off from speaker, when i put jack into hole, but no sound in headphones. 

And after notebook sleep - lost touchpad and sound until power off

add SSDT-ALC256.aml to /EFI/Clover/ACPI/Patched

and CodecCommander to /L/E

Repair permission and rebuild cache

Note: you'll have to add SSDT-ALC256.aml to the SSDT sortedOrder in the Config file

 

That's for sound but as far as touchpad after sleep, I don't have a fix.

Seeker_pl might have to chime in if he's having the same issue.

CodecCommander.kext.zip

SSDT-ALC256.aml
