HD630 HDMI Audio can not work (Lenovo RUI 7000)

[Chocofate]

My laptop is Lenovo RUI 7000 :

CPU: i5-7300HQ
Chipset: HM175
SDD：Samsung NVMe 128GB/Kingston SATA 128GB
Graphic：Intel HD Graphics 630/Nvidia Geforce GTX 1050 2GB
Audio：Realtek ALC3248 (ALC235)
Lan：Realtek 8111H
WIFI & BT：BCM94352Z
USB：left , USB 2.1x1/right , USB 3.0x2

My IntSpeaker/IntMic/Headset can work correctly with AppleALC or patched AppleHDA.

I use AppleALC this time but it is the same when I used patched AppleHDA.

My audio can not make a sound after I put FakePCIID_Intel_HDMI_Audio.kext in clover.

Audio in control panel is correct but the play button will become pause when I tried to play any music.

I added Board-ID to AppleGraphicsDevicePolicy.kext and I used KexttoPatch change connecter type to HDMI.

My screen will be black after I pull out HDMI.

There is no HDMI audio device in my system control panel when I insert HDMI.

My HDMI audio can not work.

I followed this thread:
https://www.tonymacx86.com/threads/...o-sandy-ivy-haswell-broadwell-skylake.189495/

Checking for "hda-gfx"="onboard-1"

Checking layout-id: I have only HDEF.

Checking the framebuffer: There will be a new device named AppleBacklightDisplay under framebuffer@1 when I connect HDMI.

Check under HDAU for FakePCIID loading: I do not know how.
I just put FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext in clover.

I attached terminal output file, clover file and IORegistryExplorer file as a ZIP.

Thanks .

Your ioreg shows no HDMI monitor connected. No expectation of HDMI audio without an HDMI device plugged.
You should try without FakePCIID_Intel_HDMI_Audio.kext (it is not always required and may actually break HDMI audio).

Check under HDAU for FakePCIID loading: I do not know how.

HDAU is present only for Haswell/Broadwell.

I just put FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext in clover.

Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.

Thanks for your help.

It is fixed after I follow the guide about display override but HDMI audio still does not work .

I delete FakePCIID_Intel_HDMI_Audio.kext and put all my kexts into /L/E .

MacBookPro14,3 is a poor choice. Use MacBookPro14,1 or MacBookPro11,1.

Your kextcache shows conflicting audio implementations/methods:

kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext PinConfigs.kext
kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext AppleALC.kext
kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext aDummyHDA.kext

aDummyHDA.kext should not be combined with AppleALC.kext.

Sorry for my carelessness.

I forgot to delete aDummyHDA.kext after deleting patched AppleHDA.kext.

Now,It is fixed.

The problem is still here.

I saved ioregistryexplorer file after I inserted HDMI.

I changed MacBookPro14,3 to MacBookPro14,1 but my audio can not make a sound .

I tried different layoutID but no use .

My recommendation would be to use patched AppleHDA (aDummyHDA.kext + Clover patches).
I don't use AppleALC, so not sure what you need to do to implement HDMI audio.
If you insist on AppleALC, you might refer to the AppleALC github README/wiki.

I tried both ways,but the result is the same.

Now I use patched AppleHDA.

Audio in control panel is correct but the play button will become pause when I tried to play any music.

Your ACPI configuration is wrong.

It seems that there's a lot of work to do.

I can not reply quickly next time.

Thank you.
