Are you sure your audio is ALC293 and not ALC256?

Here, replace the Config file and DSDT.aml with the attached

 

Once booted, do the following:

Remove the following kexts from /L/E

AppleHDA_ALC293.kext

 

Remove from /S/L/E <- duplicate from /L/E

EAPDFix.kext

AppleBacklightInjector.kext

ACPIBacklight.kext

 

Add to /S/L/E

VoodooI2CHID.kext & VoodooI2C ( you already got this one)

Repair permission and rebuild cache

Reboot

Disable Legacy Option ROMs if you have it enabled

You still have duplicates kexts, look at the kextcache log...

Remove from /S/L/E

  • AppleBacklightInjector.kext
  • AppleALC.kext
  • FakePCIID_Intel_HD_Graphics.kext
  • FakePCIID.kext
  • FakePCIID_Broadcom_WiFi.kext
  • BrcmPatchRAM2.kext
  • BrcmFirmwareRepo.kext

Remove EAPDFix.kext from /L/E and replace it with CodecCommander.kext for audio

Repair permission and rebuild cache
