Hello.
I'm still on OS X 10.11.6 (there is no possibility to flash BIOS at this moment). But I tested DSDT.aml + AppleALC-OZM. New audio devices are found on my PC, but no sound through their. Sound Blaster X_Fi Go_ Pro is my USB sound card. It is works fine.
The second problem with graphics. I use Intel i5-4690 + internal video Intel HD 4600. I have some freezes on boot process (see attachment). After 15 sec it becomes normal. IntelGraphicsFixup kext doesn't resolve this problem.
UPD1: I don't have any additional changes on Defaults.plist like AAPL,ig-platform-id. My Defaults.plist (with hidden serials and HardwareSignature) in attachments.
UPD2: I changed AAPL,ig-platform-id = 220332035, DisableIntelInjection = false, DisableNvidiaInjection = true - there are no any changes.
