Dell Alienware 15 R3

[RehabMan]

But I can only see the volume control gets enabled, and I can drag it around as well, but no sound what so ever.

Your patched AppleHDA components are probably not patched for your codec.
Likely the PathMap is wrong.

In addition to the other things mentioned in post #99.

I won't go searching multiple posts for the "Problem Reporting" info.
Please attach all data in one reply.

Also, avoid editing previous posts when information is requested.

Note: Your ioreg shows audio working. You will need to describe in detail what your issue is.

And.. ioreg/Clover/etc shows other obvious problems:
- CPU PM not implemented correctly
- ACPI not patched correctly (no accommodation for _OSI("Darwin")), suggest _OSI->XOSI + SSDT-XOSI.aml
- drivers64UEFI is wrong (OsxAptioFix*.efi are mutually exclusive)
- you're injecting kexts that are already installed (InjectKexts should be "Detect")

Sorry, will pay attention double check before posting, not to edit previous posts.
I will try to fix these issues, thanks.

Now I tried to fix the issues you pointed out:

- CPU PM not implemented correctly
- ACPI not patched correctly (no accommodation for _OSI("Darwin")), suggest _OSI->XOSI + SSDT-XOSI.aml
- drivers64UEFI is wrong (OsxAptioFix*.efi are mutually exclusive)
- you're injecting kexts that are already installed (InjectKexts should be "Detect")

I have some questions now...
- How should I patch the AppleHDA then? It seems patching AppleHDA manually is very complex...
- You said that my internal display is on Nvidia, not Intel, so is it possible to use the Intel HD630 instead of Nvidia?(maybe disable Nvidia?)

And about patching SSDT, I noticed that SSDT-15 corresponds to my Nvidia card.
If I want to disable Nvidia card , I will just have to add these two lines in \_SB.PCI0.PEG0.PEGP._INI:

External(\_SB.PCI0.PEG0.PEGP._OFF, MethodObj)
_OFF()

Then save as aml, move to CLOVER/ACPI/patched, set DropOem=true inside config.plist, right?

Thanks.

- How should I patch the AppleHDA then? It seems patching AppleHDA manually is very complex...

See FAQ/google. Yes.. it is very complex. You will also need to read the Intel HDA spec.

- You said that my internal display is on Nvidia, not Intel, so is it possible to use the Intel HD630 instead of Nvidia?(maybe disable Nvidia?)

I don't have your laptop, so you will need to conduct experiments (BIOS settings, experiments in Windows, etc).

And about patching SSDT, I noticed that SSDT-15 corresponds to my Nvidia card.
If I want to disable Nvidia card , I will just have to add these two lines in \_SB.PCI0.PEG0.PEGP._INI:

Then save as aml, move to CLOVER/ACPI/patched, set DropOem=true inside config.plist, right?

There seems to be a problem wit applehda wit all the Dell related laptops with Kaby Lake. I have a XPS 15 9560 with the same codec alc 3266 (alc 298) and have the same issue and nowhere have I found a solution. I've also tried many of the steps rehabman has mentioned in this thread.

Did you remember FakePCIID.kext + FakePCIID_HDMI_Audio.kext?
Some KabyLake computers need it...

With NvidiaGraphicsFixup installed, the web driver finally works...

I guess your signature is inaccurate then... and you really don't have HD630...

Would these kexts also affect audio on a Skylake build? I am having the same exact audio issue with my Alienware 17 R4. I have volume controls and microphone, but no sound whatsoever out of the speakers.

Yes.
Always worth a try.
