speakers in system preferences->audio are missing
Attach cloverALC script output
IOReg says realtekALC.kext did not load, Clover says it loaded the kext.
Are there any other realtekALC.kexts installed?

Remove dsdt/HDEF/hda-gfx as shown: (comma is important, remove)
Code:
,

                        "hda-gfx",
                        Buffer (0x0A)
                        {
                            "onboard-1"
                        }
dsdt edits are not recommended; especially, edits prepared for older BIOS.

Hi Toleda,

CloverACL script output attached as required.
I installed only 'audio_cloverALC-120_v1.0d'. Nothing else

Regarding 'remove dsdt' I would like to be sure that you are asking me to edit DSDT.aml with DSDT editor. Can you confirm me?

Thanks

Yes, remove only the code noted above.
To be clear, all edits present in your dsdt are not appropriate for a 200 Series motherboard. For example, "Intel 8 Series Chipset Family USB Enhanced Host Controller #1" Device does not exist, edit is ignored.
Recommendation: remove the edited dsdt.

Hi Toleda,

Ok. I tried to edit EFI/CLOVER/ACPI/origin/DSDT.aml with DSDT editor. Folder 'Scope_SB.PCI0 -> Device HDEF but I didn't find 'hda-gfx'. Can you look the screenshot attached?


Same file in EFI/CLOVER/ACPI/patched/ is not possible to edit with DSDT editor. Message is 'Pairs of brackets don't match. Tree not updated'.

Thanks

Ignoring Post #3170 advice.
Native dsdt does not have hda-gfx, patched dsdt does. The patched dsdt is the problem.

How did you edit the dsdt installed in EFI/CLOVER/ACPI/patched?

No idea.
If DSDTEditor worked previously with the native dsdt, it should still work with the native dsdt.
Waste of time.

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

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
