No Sound - Realtek ALC AppleHDA [Guide]

[toleda]

problem I have is videos on safari play but with no sound. I'm not sure why?

No ideas. Suggest an install over the existing install, did a lot of damage with your experiments.

can I provide you with the codec dumps

I know what is in the 888 dump. The files tell me what you did wrong; no files, no support.

I was about to reinstall everything and now the sound works on everything except one website that says my media player on the browser is not compatible. Thank you very much Toledo. You have been instrumental in my first build!!!

1. Audio worked. Had some glitchs and I messed up trying to fix it and got no audio. Cant go back.
2. macOS Sierra 10.12.6 / mobo GA-H270m-D3H / BIOS v.F6 / Intel i7 7700 / nVidia Geforce 1050 Ti
3. Method Used:Before You Install Audio - Desktop/Realtek/AppleHDA [Guide]

1. Drivers on Multibeast -> RealtekALC892 + 100 / 200 Series Audio​

4. Adjunting copy of IOReg
5. No AppleHDA kext.
6. No AppleHDA kext. When I use the method to restore the native kext to install it again system crashes and I have to enter on recovery mode to delete it.
7. No Kernel Sound Assertions on console/all messages (maybe im doing it wrong)
8. Adjunting screenshots of DPCIManagerStatus, Audio Hardware, Audio Outputs.
9. No chameleon Installed
10. Adjunting config.plist
How am I supposed to upload the bootlog here?
11. Genius SW-S2 1200 speakers connected to the green port on the motherboard. Internal Speakers selected on audio output.

Also adjunting a screenshot of the codecdetect.command.

Thanks for the help!

messed up trying to fix it and got no audio

892 audio is configured correctly
Kaby Lake audio fix is not working, try a different method.

Tried method 1. with no success.
Deleted FakePCIID.kexts from Extensions and tried method 2.
Did method 2 with no success. Messed up with the config.plist file and had to do a reinstall.
Now with a fresh install tried method one and didnt work.

What is the correct procedure to delete kexts from method 1 and fix the patches of method 2 before jumping onto method 3?

Move FakePCIID kexts to trash. Occasionally, installing newly downloaded kexts solves the problem
Install backed up files, otherwise, remove edit added

Reply with new files.

I removed the files and installed SSDT-HDEF-HDAS-2.aml. My dual screen set-up promptly stopped working! (Currently running with my Displayport monitor only, turning on the HDMI monitor after booting to the desktop no longer works). Been trying to redress that problem without success, hence the delay in getting back on this issue, and may also explain some changes to the files (attached).

I managed to make it work with a fresh install with FacePCIID kexts. But I have a bug. Every x amount of time (can be every 10seconds or every minute) I get a sudden loss of audio for half a second. Do you know what it could be? I can make a recording of the problem if it helps.

EDIT: It doesn't happen if I connect the speakers to the case headphone port. It only happens if it is connected to the green MoBo port.

SOLVED: Turning the System definition from Mac Pro to iMac solves the problem.
