The internal speakers / lineout reversal is intentional.

This is the only way lineout back and HP front work in switch mode (automatic detection and switching when HP is plugged in).
Which devices work with the trial version?
Please report!


Thanks for the clarification on the Internal speakers / lineout reversal.


Lineout back (green, as IntSpeaker) YES
HP front (black, SwitchMode, if plugged in) YES
Internal speaker (as lineout) YES
Mic back (pink) YES - as Upper Internal Microphone in Sound Prefs Input
Mic front (black) YES - as Lower Internal Microphone in Sound Prefs Input
LineIn back (blue) YES
In short everything works exactly as it should, for which many thanks once again.

Hmm, as I suspected the skeletal device names shown in System Profiler were entirely my fault!


I'd grabbed the latest 10.13.2 AppleHDA.kext from my archive in too much of a hurry and it must have been a partial file from the 10.13.2 delta update and thus incomplete.  Once I checked the size and then replaced it with the full 10.13.2 AppleHDA.kext from another machine all the device names returned to normal.  This was simply my own incompetence and nothing to do with MacPeet's excellent trial AppleALC.

Try this with LayoutID28:
Change back to the original AppleHDA for this experiment !!!
Rockey12 had reported it only works with CodecCommander! ???

Thank you very much MacPeet.  With this new trial version sound certainly works well with HS 10.13.2 and its original AppleHDA.kext.
In my earlier post I had forgotten to say that I was using your earlier test version with Codec Commander, and I'm using it still with this latest version.
I do seem to have one issue in that System Profiler is now displaying the audio device names incorrectly.  I don't remember this happening with the earlier test version.
The last entry is my ESI Juli@ sound card.  Perhaps I've done something wrong here as I note bilbo reported the same Internal Speakers / Line out reversal as with the earlier patched AppleHDA.kext


I'd like to encourage more volunteers to help test this useful addition so that it may be properly validated and I hope added to the official AppleALC release.


Thanks again,

I can re-create a trial version for HighSierra when you're ready for test reports.


That would be terrific, thank you very much indeed.  I'd be more than happy to test a new trial version for High Sierra and I'm sure many of us here would appreciate it.


Thanks again,

Thanks so much for the help. 


Audio is still not working. 


That is what I did:


- I installed attached kexts in their respective folders. (I keep my original AppleHDA)

- Add 28 in inject audio section in config.plist. (trying with reset hda option activated and deactivated)

- Add -alcbeta to bootflag in clover (also I tried without)

- Add HDEF device (in my dsdt, into _SB / _PCI0 branch)


After reboot, I can hear some "clicks" on boot, (like when I boot with El Capitan with audio working), and the device is shown in system profiler , but I think it´s something cosmetic. Any device is shown in audio panel control.


Forgive me for coming late to this discussion but for a short while I was successfully using a test version of AppleALC version 1.1.2 with modifications for the HP z400/600/800 ALC262 codec by MacPeet and generously provided by him as Archiv.zip in post #1042 of this thread.

This was on my z400 running High Sierra 10.13.1 so I needed the -alcbeta boot flag.  Initially it was paired with Lilu 1.1.5 and so -lilubeta was required, but later I used Lilu 1.1.7 which didn’t need the beta flag.  Layout ID 28 in dsdt is also necessary.

On reaching the betas of 10.13.2 and 10.13.2 itself then older versions of Lilu would no longer load while the new Lilu 1.2.1 is no longer compatible with AppleALC versions as old as 1.1.2.

At this point I had to revert to a patched AppleHDA.kext like the one Rockey12 has kindly posted above, since MacPeet’s excellent changes to AppleALC for our ALC262 were I think inteded for testing only and so were never incorporated into vit9696’s official AppleALC sources.

Can I first of all thank MacPeet for his work and also suggest that if he approves his code might be submitted to vit9696 for inclusion into the official AppleALC distribution?  That way it should conitnue to work with future High Sierra releases on all our HP z400/600/800 workstations.
