Hello

i try also to enable SPIDIF out from a bracket added to my mobo with a cable from SPDIF out pins of the mobo. Under windows i've got sound from this SPDIF bracket

My mobo : GA Z77 DS3H, ALC887, OSX 10.12

I installed first audio on clover with audio_clover_120.command, with ALC 887, layout ID 3, clover mode. Analog sound is working.

then i followed the toleda customization guide :

Edit Platforms.xml/zml
1. Open Item/PathMapID
2. Open the current SPDIFOut (last item)
3. Edit this path map as follows:
4. Current:
⁃ Item 0/NodeID/Number/30
⁃ Item 1/NodeID/Number/6
5. New:
⁃ Item 0/NodeID/Number/17
⁃ Item 1/NodeID/Number/16
B. Edit HDAHardwareConfigDriver/info.plist or realtekALC/Info.plist
1. Open Item/CodecID
2. Verify CodecID/LayoutID
3. Edit ConfigData (1150 only, edit each entry, 21 to 01)
⁃ Find: 21171cf0 21171d00 21171e00 21171f40
⁃ Replace: 21171ca0 21171d01 21171e43 21171f99
⁃ Find: 21e71c90 21e71d61 21e71e4b 21e71f01
⁃ Replace: 21e71cf0 21e71d00 21e71e00 21e71f40
C. Save, install and restart

So
1) in platform.zml.zlib, i changed in 887 path, last item, the 2 nodes from 30/6 to 17/16
It does not work after reboot
2) then in EFI/...10.12/realtekALC.kext/.....Info.plist, i did the patch of ConfigData in 887 codec, layout 3
Audio disappear after reboot !!!!

When i put back the previous Info.plist, of course sound is back again.

Could you please help me ?

Included the patched file

Thanks in advance
