Realtek ALC256 - Devices detected, Input mic works, Output No Sound.

PU: Intel i7 9750h

GPU: Intel 630/Nvidia RTX 2060 (disabled with WhateverGreen bootflag)


Motherboard/Laptop model: Razer Blade 15 Base 2019 (RZ09-0300)

Audio Codec: Realtek ALC256

Ethernet Card:

Wifi/BT Card: BCM94360NG

What guide/tool followed: OpenCore (ACPI, kexts, and slightly tweaked config.plist from here)

What part I got an issue with: Have not been able to get audio working.

Tried with VoodooHDA.kext - no audio input or output devices detected.

Tried with AppleALC.kext - layoutid 13 and 28 show input and output devices, but only the mic input works. No sound comes from output device and only buzzing noise when plugging in headphones to audio jack.

In windows, audio devices show up as Realtek Audio and THX Spatial Audio (which I think it just Razer's synapse setup for surround sound)

Hackintool state "You may require Spoof Audio Device ID"

What files/config I am using:
