I used kext from this post

 

But it does not load on Sierra 10.12.0

It shows error:

Executable file doesn't contain kernel extension code (no kmod_info symbol or bad Mach-O layout).:	1

Only mention of this error was some bug in 10.6

 

Any ideas?

Managed to get the sound working using patched AppleHDA by insanelydeepak from here with HDAEnabler's kext

 

(removed original AppleHDA from S/L/E & installed patched to L/E )

Edit

Each update requires removal of original AppleHDA, I suppose there could be a way to patch it with Clover on the fly, but did not check it yet
