Update: Rebuilt system and kexts caches on my startup disk with KCPM Utility Pro, restarted and now all is working, including the digital S/PDIF outputs! Hopefully it stays stable.

 

Thanks Toleda!

 

Note: I also tried to "Repair Permissions on Entire Disk" with this utility, but it never finished [3+ hours], so perhaps something changed in 10.11.1.

 

Hello I try also to enable SPDIF output on added bracket to the mobo, so I need to edit platform.zml.zlib and realtekALC.kext/...Info.plist

 

But unfortunalety it doesn't work, I dont know why, I did the same fix like Anachronaut did with the help of Toleda

 

My mobo : GA Z77 DS3H > ALC 887, layout 3 - analog sound working well

 

1) I switch the 2 node id of last item in 886 path of platform.zlib

2) then I patched the info.plist of realetkALC.kext in clover/kext folder

 

Here attached the 2 kexts, before then after the patch :

- AppleHDA.kext

- RealtekALC.kext

 

Also the picture of the patch of Platform.zml

 

Here are the ConfigData, codec 887 (283904135) layout 3

After:

21471C10 21471D40 21471E11 21471F90 21571C20 21571D10 21571E01 21571F01 21671CF0 21671D00 21671E00 21671F40 21771CF0 21771D00 21771E00 21771F40 21871C40 21871D90 21871EA0 21871F90 21971C60 21971D90 21971E81 21971F02 21A71C50 21A71D30 21A71E81 21A71F01 21B71C70 21B71D40 21B71E21 21B71F02 21E71CF0 21E71D00 21E71E00 21E71F40 21F71CF0 21F71D00 21F71E00 21F71F40 21171CA0 21171D01 21171E43 21171F99 

 

 

But whatever I do, no sound anymore detected in pref panel after reboot.

If I replace with the stock Info.Plist, sound back, but of course spdif patch doesn't work

 

Coud you please help me ?

 

Thanks !!!

GA Z77 DS3H > ALC 887, layout 3 - analog sound working well

 

1) I switch the 2 node id of last item in 886 path of platform.zlib

Apologies for the delay in replying

PathMapID = 387 for 887/Layout 3, not 887 (Layout 1)

Restore Platforms and re-edit the correct PathMapID

Hi toleda,

 

I need some help I guess:

10.11.6, smbios mac pro 6.1,

I'm on a Asrock X99M with ALC 1150, but with some minor changes to my dsdt (mac pro 6.1 smbios with gtx 970), my gtx1 graphics is not added with original dsdt, so I've changed my dsdt:

changed BR3A.H000 to BR3A.H00Y,

changed BR3A.H001 to BR3A.HDA1

see attached dsdt

with this change I was able to add GFX1 to BR3A device tree to solve the NVIDIA Driver issue (pikes AppleGraphicsDevicePolicy patch in config.plist does not work for me).

I've attached the dsdt as well as the ssdt.

 

but now I've managed to destroy my working audio configuration.

I've followed your description on page 1 post 1 for x99 (steps 1-5) with

 

1.Rename dsdt/ALSA to HDEF (Select one method) (ive using both methods clover config and ssdt.aml)

2. restart (alza is hdef on PCI0/AppleACPIPCI/HDEF@1B

3. Install Realtek ALC Audio (see Realtek ALC Installation Methods)

Method I used: audio_clover_alc command with realtekALC.kext in /clover/kexts/others (attached)

4. Add x99 HD Audio device_id

Method I used: first try clover config kexttopatch

send try: patched appleHDA.kext

 

still no sound in the systempanel. no hdmi audio as well.

I'm just lost

I've attached every stuff you requested in problem solving area.
