No Audio Devices - Realtek ALC AppleHDA [Guide]

[toleda]

Do you know some other system to edit DSDT file patched?

There is no reason to edit a dsdt, use clover patches or ssdts instead; remove edited dsdt.
For audio, install ssdt_hdef-1-hdmi-with_ioreg:hdef.zip

I have an old series 4 board running 10.11.6. All is great except audio.

This is a Gigabyte GA-EG45M-UD2H with Core 2 Quad Q6600.

This board has the ALC889A codec (address 2).

I boot clover v2.3k_r3998. No SIP issues.

I've tried many patching methods but now see that I have the dreaded phantom codec.

From DPCIManager->Status ...

0x80863A3E, 0x1458A102, 0x10EC0885, 0x0101, Realtek ALC889A
0x80863A3E, 0x1458A102, 0x00000000, 0x0000, NULL Codec

Has anything been figured out for this ... for El Cap ?

Thanks in advance

Ok. I tried to sostitute the SSDT file in /EFI/CLOVER/ACPI/patched with the new one attached as indicated but after the reboot the situation is the same. Always only 'Soundflower' speakers shown in system preferences -> audio output

the situation is the same.

All the files changed and not one file attached, useless post.

Sorry toleda, I didn't understand that was necessary to upload all the reporting files again.
I provided them.

Operations: I deleted the file SSDT.aml in EFI/CLOVER/ACPI/patched and substitute with SSDT-HDEF-1-HDMI.aml
After that I rebooted the pc. In system preferences -> audio output is shown always only 'Soundflower 2ch'.

Attach all the files required in the guide for SSDT installation.

Thanks

Removed DSDT

Attach EFI\CLOVER\kexts\Other\realtekALC.kext
Is there another realtekALC.kext? .../kexts/10.12 or /L/E or /S/L/.E?

In the directory EFI\CLOVER\kexts\Other\ there is only realtekALC.kext

From 10.6 to 10.11 directories are all empty
