The audio jacket works fine (not amazing quality) on Windows even on the front port output. So it's installed and is functional,

Thanks Toleda.
I've now copied "SSDT-HDEF-HDAS-1.aml" to EFI/CLOVER/ACPI/patched.
Then, ran script. "audio_cloverALC-120_v1.0f1 3.command".
HDMI audio is working again now which is handy. No audio working still via headphones on motherboard green port or front panel.
When attempting to play music from iTunes, or other media like movies from VLC etc, media does not open/play, playhead does not move in timeline. When switching to HDMI audio, playback resumes as normal.

Sierra 10.12.4
Asus Z170M-E D3

New copies of error reporting files attached. Thanks for your time.

AppleHDA.kext is damaged. Restore native AppleHDA.kext.

AppleHDA.kext is damaged. Restore native AppleHDA.kext.

Ok, ill have a go at that. Should I use the guide below (works for 10.12.4?), or is it possible to install a new copy of the kext using DPCIManager or a similar kext utility? If so, where can I get a copy of the Kext?

Should I use the guide below

Yes. That is where you get the "copy" of the kext. A kext installer is required to install any kext.

Looks like Sierra has updated now to 10.12.5 on the Apple Store. Will this work, or should I download a 10.12.4 version again from another source to restore AppleHDA.kext from?

 

[toleda]

Will this work

Assuming 10.12.5 is installed, yes.

 

[thomasbl83]

Assuming 10.12.5 is installed, yes.

10.12.4 is currently installed, have not updated to 10.12.5 yet.

 

[toleda]

10.12.4 is currently installed

Installing native 10.12.5 AppleHDA.kext on 10.12.4 disables audio.

Hi,

I have been having a lot of problems getting my audio to work. After lots of attempts, I now get some audio devices show up in my sound preferences however no sound will play; YouTube videos constantly buffer and media files immediately stop playing after clicking play.

I originally installed the audio drivers through multibeast and used Voodoo but I backed this out because I only got high pitched hissing out of the audio ports. After having no luck with this thread, I used this thread (Post install / Audio section) to set audio up through HDMI and I have now successfully got audio working through display port only.

I then came across post #1498 by thomasbl83 in this thread who said "playhead does not move in timeline." which is exactly where I currently am. Reading Toleda's response, I restored my native AppleHDA.kext using this guide: https://github.com/toleda/audio_RealtekALC

Unfortunately I am still in the same position and I am out of ideas. I am assuming this is config related but I dont know where to look anymore.
