No IOReg/HDEF; BIOS/audio/disabled

[daveodwyer]

Hi,

I have been trying to understand why my audio will not work - mobo P8P67 - audio ACL892.

I am receiving the following error: Agreement The audio_realtekALC-110 script is for personal use only. Do not distribute the patch, any or all of the files or the resulting patched AppleHDA.kext for any reason without permission. The audio_realtekALC-110 script is provided as is and without any kind of warranty.

File: File: audio_realtekALC-110.command_v1.0h /Users/dave/Downloads/audio_cloverALC-110_v1.0j.command: line 177: [: /Volumes/El: binary operator expected Password: Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem No system files were changed To save a Copy of this Terminal session: Terminal/Shell/Export Text As ... logout Saving session... ...copying shared history... ...saving history...truncating history files... ...completed.

Everywhere online states that I should confirm that Audio is enabled in the BIOS and it is.

When I use a tool DCPIManager to inspect the codec ID, it shows no ID, however 2 devices appear in the list with ids:

1) Audio Device: 0x80861c20 2) Audio Device: 0x1002AA58

I have also tried the audo_cloverALC-110 command and it is also returning the same "No IOReg.... etc" error.

I am very new to working with hackintoshes, so please excuse my ignorance if I am missing something.

dsdt does not have device HDEF, required for OS X audio. Install this ssdt: https://github.com/toleda/audio_ALCInjection/blob/master/ssdt_hdef/ssdt_hdef-1-no_ioreg:hdef.zip If BIOS is 3xxx, no AppleHDA audio; 2xxx works as expected.

Hi @toleda , I am having a similar issue, No IOReg/HDEF; BIOS/audio/disabled , my board is GA-EP45-UD3P (old lifehacker board), any advice on how to get OS X to see the onboard audio? in BIOS settings the only thing i can find is Azalia Audio which i have set to Auto (as opposed to "Disabled"). thanks!

PS I'm not sure I'm posting in the right place, I am kind of lost trying to get this audio to work, believe it to be the last step in getting my hackintosh up to date.

Apologies for the delay. See https://github.com/toleda/audio_ALCInjection, add HDEF.

This solution worked great for me on ALC 1150. Thank you!

Hi @toleda and thank you for your work, I've a Gigabyte GA-Z170X-UD5 TH mobo which is supposed to work with Realtek ALC1150 codec (that I selected in Multibeast in the audio drivers config both the times) and have already the High Definition Audio. I just build up my hackintosh, the boot is made with Unibeast and Multibeast and I tried at first to install Sierra, but since the only version of the system I could provide at first was the VERY LAST ONE, I had immediately troubles with the codec for the video card, and the audio was not working, even running audio_cloverALC-120_v1.0d.command, I didn't even ask to insert the password, it was already giving me an error, saying that my os x was not supported.

So, I found a version of El Capitan from an old download I did, and I downgraded to os x 10.11.6, video drivers for my nvidia video card are working, BUT STILL NO AUDIO.

So i tried to run audio_cloverALC-120_v1.0.d.command again, and I was allowed to insert my password, but still, no audio recognised and the following error advice:

OK to patch Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem No system files were changed To save a Copy of this Terminal session: Terminal/Shell/Export Text As ... logout Saving session... ...copying shared history... ...saving history...truncating history files... ...completed.

[Process completed]

the most confusing part for me is that I already am supposed to have a mobo which supports hi def audio... and so I don't find any solution in the previous answers to this similar topic.

I'm also an absolute beginner, so maybe I'm missing something you're given for obvious... so sorry for that... but any help would be incredibly appreciated <3

thank you!

macOS does not support 100 Series HDAS. Fix: install https://github.com/toleda/audio_ALCInjection/blob/master/ssdt_hdef/ssdt_hdef-1-100-hdas.zip

@amark89 macOS does not support 100 Series HDAS, see ssdt fix above.
