No change. Still no audio and the NULL Codec is still listed in DPCIManager, HDEF has a blank CodecDevice and AppleHDA.kext stops after a while.


This is my final solution,, please upload your CLOVER folder again,, and IOREG output

Attached are the CLOVER folder, IOREG output and a file containing the Linux files from /proc/asound that people usually provide as codec_dump.txt (I also provided this in my original post when I started this).

HDAIDT.kext was created by @bcc9 for the Dell XPS 1340 (that’s where I got it). Maybe he can provide a solution.

I have checked the Pinconfig, layout and platform. Different is about binary patch,, your old configuration use "8419D411" to be renamed to "75761D11" instead "8B19D411".
And i tried various combination, but still there is no patern why is it working and not after reboot.

@najeeb_anwer
Where is the problem?
Codec_Dump of the computer?

Which computer? Name? No signature completed!
Inject LayoutID with Clover or with patched DSDT?
You work with HighSierra?
You work with original AppleHDA and AppleALC + Lilu?
Delete all kext-to-patch entries for AppleHDA in Clover!
Dummy.kext or realtekALC.kext are not in the system? Neither in Clover, nor in L/E or S/L/E? If yes, then delete!
With HighSierra try also older version AppleALC1.2.7!
With older computers and new AppleALC for Mojave there are some problems with the Inject.

My laptop details are now in the signature.

 

Problem description:

I have macOS High Sierra (17G3025). I have previously been using a modified AppleHDA.kext (for layout-id 12) with AppleHDA patches in config.plist and an audio kext called HDAIDT.kext, which worked. All of this is attached to this post in file called "Dell Studio XPS M1340.zip".

I want to use Lilu.kext & AppleALC.kext. The codec (IDT 92HD73C1) appears to be supported with layout-id 19.

Originally, the problem was that the alc-layout-id was not being injected by any of the methods (config.plist Devices/Audio/Inject or Devices/Properties or by using alcid=19 at boot). @Andres ZeroCross fixed this problem by providing a modified DSDT.aml that properly injected the properties in HDEF.

The problem now is that the audio works only occasionally, but fails on reboot.

When it works, it looks like this:

image.thumb.png.b6b179c9fc3d306a1c45d46d622110e3.png

When it does not work, there is a NULL Codec present in the DPCIManager audio list and there is an empty "IOHDACodecDevice@8,1" listed in IOReg/HDEF, and AppleHDA.kext stops running after a minute. It looks like this:

image.thumb.png.b30016cfb7cf25a622cc0514d6ed44fc.png

 

Codec_Dump of the computer?

The entire contents of Linux /proc/asound is attached.

 

Inject LayoutID with Clover or with patched DSDT?

Patched DSDT.

 

You work with HighSierra?

Yes, macOS High Sierra (17G3025).

 

You work with original AppleHDA and AppleALC + Lilu?

Yes, original AppleHDA. The AppleALC I am currently using is provided by @Andres ZeroCross using layout-id 21 but the problem existed with original AppleALC and using layout-id 19.

 

Delete all kext-to-patch entries for AppleHDA in Clover!

Yes, from the beginning.

 

Dummy.kext or realtekALC.kext are not in the system? Neither in Clover, nor in L/E or S/L/E? If yes, then delete!

Yes, not present.

 

Please let me know if I need to send any more info. Thanks.

@Andres ZeroCross and @najeeb_anwer i would prefer patched applehda instead if you have lots of issue in start , then you can move to appleALC , if patched appleHDA works then is no chance appleALC couldn't work for you

 

Please see my previous post. I have had working audio with patched AppleHDA and HDAIDT.kext

can you use it again for couple of days to see same issue you are having with it ?? and what about using resetHDA in clover config.plist ??

Yes, I have gone back to using my original DSDT.aml (without the HDEF _DSM patch to inject alc-layout-id), the modified AppleHDA.kext (for layout-id 12), the AppleHDA patches in config.plist and HDAIDT.kext.

This configuration works, consistently, across multiple reboots, without problems. I have been using this since Mac OS X 10.7.

 

I think the problem is the NULL Codec that is present in HDEF which causes AppleHDA.kext to exit. I tested by removing all the related kexts (Lilu, AppleALC and HDAIDT) and the DPCIManager still shows 3 codecs listed ("IDT 92HD73C1", "NULL Codec", "NVidia MCP7A HDMI").

I don't claim to understand exactly what HDAIDT.kext does, but part of it appears to be to patch AppleHDAController.kext to remove the additional codecs. When I use HDAIDT.kext, the only codec that shows up in DPCIManager is the "IDT 92HD73C1".

 

I have not tried using resetHDA in config.plist. It is not needed for HDAIDT.kext to work properly.

I suppose I can try it when I reinstall AppleALC the next time. Hopefully, the next attempt will be when you experts have a solution to the problem. :)

 

I have attached my current patched DSDT.aml so you can check for clues about what might be causing the "NULL Codec"

This is what the system shows when I am using HDAIDT.kext:

Kext Inject in the clover on "YES", not "Detect"?

 

Please try rollback AppleHDA from 10.13.3 with AppleALC + Lilu!
Install via KextUtility2.6.6! Secure Real ApplaHDA before!
Since 10.13.4 the AppleHDA has changed massively. My old system with codec AD1984A works since then only with rollback + AppleALC + Lilu.
Please test this!

i dont think HDAIDT.kext doing any additional patches to AppleHDAController.kext except to inject file and configuration 

 

as i said earlier this could be possible your system is not in AppleHDAController.kext supported list , thats why partially working 

 

why not try @MacPeet rollback kext ?

You're right; I removed HDAIDT.kext completely and audio still works consistently. Although now I do see both the IDT and NVidia codecs listed.

 

I think the problem with the NULL Codec was due to some problem in the DSDT I was using. I have gone back to using the DSDT that I had before I started trying to use AppleALC.

image.png.51929d05ccab3e8299d88ff907e006f0.png

The only changes I have at this point is the modified layout12.xml.zlib and Platforms.xml.zlib files in AppleHDA/Contents/Resources and the 2 AppleHDA patches in config.plist.

 

I can't inject the layout-id because of the existing _DSM method for HDEF in DSDT.aml and I don't want to touch the DSDT in case it gets screwed up again.

 

Can you please add my layout-id=12 to codec IDT92HD73C1X5 in AppleALC.kext and

send me a new one to test? The relevant info is in the attached file.

I will try this in case the solution with layout-id=12 in AppleALC that I mentioned above does not work. Thanks.

It doesn't make sense, your IDT kext is contain pinconfig for your codec. How can audio work??? Your audio shouldn't work without properly pin config for your codec.

I am as surprised as you are. But here are the kexts I have in CLOVER:

And this is the working audio. I have rebooted several times and it works every time.

And this is the PinConfigurations in IODEF:

Cannot enable sound on new notebook Acer swift 3 sf314-54.

Now works everything except sound. I`ve tried all different patches, pinconfigs, ssdt-256.alc+codeccommander - nothing. Even VoodooHDA not enables this codec. 

I`ve taken dump from ubuntu, pls look in dsdt - I think there are too many HDAS sections.

DSDT.aml

codec#0.txt

codec#2.txt

you can use clover if you want to stay out of DSDT stuff
