No Audio Devices - AppleHDA Realtek Audio

Try removing and installing the patch, restart.
Reply with new files.

Ok, here is what I interpret "removing and reinstalling" to mean:
> rm /Volumes/EFI/EFI/CLOVER/ACPI/patched/SSDT-HDEF-HDAS-1.aml
> mv $HOME/Downloads/ssdt_hdef-1-100-hdas/SSDT-HDEF-HDAS-1.aml /Volumes/EFI/EFI/CLOVER/ACPI/patched/
[then reboot]

Is that correct? All the files look the same as what I uploaded. Apologies if there is something else to do when I remove or install.

No ideas. Not clear:
why Clover is installed to 2 drives.
why the EFI partitions are not named EFI.
what Clover is doing.
For 10.13 audio, suggest clean install.

I alway keep the new version and the last version of MACOS on two different physical drives so when I upgrade I can go back if something turns out bad. So I use Carbon Copy to clone the known good working partition to the other Drive then I upgrade. That is how I got to the situation I am in. I have always kept a copy of an EFI partition on the drive I am using to load an OS in case there is some issue. I can disable all of the boot drives except the one I want to load to insure the clover path I want gets used. But there is an odd thing that in the BIOS a boot entry exists for MACOS and I don't have any drives with a name like that so I am perplexed by which dive it loads when pointed there.

Ok, I managed to solve my problem by removing some of the Clover BIOS boot entries. In fact, I removed all of them except for the one for my boot drive. There were 5 different entries, 4 of which were rather mysterious to me as to what they even were.

USB is a more appropriate rescue drive

Why would you select MACOS to boot?

Hi,

I'm running Gigabyte GA-H270-Gaming 3 (which has ALC 1220 for audio) - BIOS F6 - Gigabyte GTX 1050 - i5-7600 . High Sierra installation works great - except there are no audio devices. Ideally I would be able to output via hdmi.

I'm trying to follow https://www.tonymacx86.com/threads/applehda-realtek-audio-guide.234732/#post-1606764 - which lead me to https://github.com/toleda/audio_ALCInjection/blob/master/[Guide]-Add_or_Edit_HDEF-dsdt.pdf.

I've found that I have no HDEF in my IO Registry. Trying fix using MACIASL. I've dumped my dsdt.aml by hitting f4 at the clover boot and I decompiled the dsdt.aml via iasl -da -dl DSDT.aml. Iasl does give a warning "There were 38 external control methods found during disassembly, but only 30 were resolved". Attachment has full iasl output.

When I open the dsdt.dsl file in MaciASL and compile, I get 3 errors (see attachment). Adding the Clean Compile patch does not help.

Any suggestions? My dsdt.dsl is also attached.

Thanks in advance.
