Bit of a mess in your files.
I see you have Disable Discrete graphics, but no sign of a eGPU from your Origin folder.
Can you confirm it does have a discrete card?
You have AppleHDADisabler, this prevents AppleHDA from loading....hence no audio
You have too many ethernet kexts, can you confirm system has Intel or what does it have?
NullCPUPowerManagement.kext is never a good idea if you want power management. Check also in BIOS you have Legacy Option ROMS disabled
I see you have USBPort.kext, is that generated from FBPatcher with this system or you got it somewhere else?
Do need USBInjectAll if USBPort.kext is present.
SSDT-UIAC-ALL.aml, is that from this system?
