No Sound - Realtek ALC AppleHDA [Guide]

[epalzeo]

Hello Toleda

I'm progressing with your help but that's not ok. (excuse me, if posted on GitHub also before seeing this thread)

Here's my config
Gigabyte Z77 DS3H, EFI BIOS, i7
Bracket connected to the mobo with 5V supply through USB pin, tp have SPDIF output
SPDIF working under windows
ALC887 normally, but shown as 888b under DCPImanager.
I used audio_cloverALC-120_v1.0d.command, it detects 887

I can have analog audio under OSX, but no SPDIF output through OSX. So I used the customizing guide, procedure 7 to substitute SPID output.

I used layout 3 before, but Toledo suggest me on GitHub to switch back to layout 1, which I did.

I patched the 2 kexts :
-AppleHDA, platform.zml.lib, pathID 887, with pins 30/6 to 17/16 like shown in the customizing guide
-realtekALC for clover (10.12 folder), with the configData patch provided but the guide

Here are all files attached.

Analog audio is now working under OS X with the 2 kexts patched, but the SPDIF output is not working.

So I'm looking for the mistake I did

Thanks in advance

Intermittent is not related to wake/sleep. Off topic.
Verify config.plist/CPU has no frequency settings and UseARTFrequency/NO

Verified no frequency settings and UseARTFrequency is off/no.

Still getting sound outages. Played sound in YouTube on Chrome, closed Chrome and then no sound...doesn't happen every time though I just tried and lost sound.

Rebooting gets it back.

If you're open to one more try...when the sound went out today, this appeared in the console:
