[solved] No sound with AppleHDA injector

[STiX_MAC]

i tried to patch my AppleHDA with a dummy kext from rehabman's script but for some reason i don't have sound although the symbol is there and the volume is changing but there are no inputs/outputs. I patched the HDEF and HDAU and i have the correct layout so i don't think that's the problem. Attached the files including my codec files.

Don't forget to boot without caches, rebuild cache, then boot normally.

i did that but still the same, although i installed a kext and then rebuild cache

Might be a problem in your ACPI setup.
Look what happens if you try to disassemble your patchmatic -extract output with 'iasl -da -dl *.aml':

ACPI Error: [_DSM] Namespace lookup failure, AE_ALREADY_EXISTS (20161210/dswload-462)
ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20161210/psobject-310)
Could not parse external ACPI tables, AE_ALREADY_EXISTS

well i'm kinda noob on ACPI. what does this mean?

It means you have a duplicate _DSM method somewhere.
In your case, I think it is due to conflicting ACPI/patched content and Clover config.plist settings.
You have config.plist/ACPI/SSDT/Generate/PluginType=true.
It conflicts with SSDT-PluginType1.aml.
Use only one or other other, not both.
See guide for details:

Also, the Generate/APLF, Generate/APSN you have as 'true'... are wrong. Remove.

I did the changes you mentioned and still the same. I booted without caches, rebuild cache, then boot normally but still no change. What the chances are that the SSDT-HDEF and SSDT-HDAU have issues? the layout-id is 3 but i use 13 through the \RMCF.AUDL. Attaching files.

ok i managed to fix it by changing the codec layout to 3 and creating again the AppleHDA injector and now works.

Your patchmatic output now disassembles cleanly with: iasl -da -dl *.aml
You should check that your AppleHDA actually uses layout-id=13. Most patched AppleHDA for laptops use 3.

Seems this can be marked solved.
