Ok, could be your audio codec is different than 5480. Reinstall VoodooHDA and then post screenshot of Status with DPCIManager.

This is what I currently have for 10.12.6 with latest security updates but on BIOS A18 See if it helps. Replace into /EFI/Clover E7450_10.12.6_A18.zip

do you have the installer available? Try booting that and then selecting the drive to boot boot with verbose + debug 0x100 mode

how were you able to attach the Clover folder? You could update the files from this attachment v4411

I see you have 2 different PS2 kexts. VoodooPS2Controller by Rehabman (Synaptics) in /E/C/k/Other and ApplePS2SmartTouchPad (Elantech) by EmLyDinesh in /S/L/E. Do you know if you touchpad your system have? Alps, Synaptics or Elantech? You need to remove one or the other. I see you also have 2 different audio kexts: AppleHDA_ALC256B and VoodooHDA. AppleHDA_ALC256B not working for you? Did you check the BIOS for Legacy Option ROMs?

and what version of Clover? try upgrading to latest v4411

what version of BIOS are you on? you think it updated to High Sierra?

Make sure you don't have Legacy Option ROMs enable in the BIOS, if you do disable it. Follow instructions from here to debug issue gen_debug -sysprofile

post your system's spec. Does it have Nvidia or just HD 5500? Which bootpack did you use? What version of BIOS? Which version of Clover? Post your Clover folder for review

post the screenshot to be more clear

Try repairing permission and rebuild cache

Add latest CodecCommander.kext to /Library/Extensions Repair permission and rebuild cache

Try this guide and files?

You have these in /E/C/kexts/Other and in /Library/Extensions. I call that duplicates ACPIBatteryManager FakePCIID FakePCIID_XHCIMux FakePCIID_Intel_HD_Graphics IntelMausiEthernet VoodooPS2ControllerR6 FakeSMC

Replace kext with this one AppleHDA_ALC292.kext.zip Repair permission and rebuild cache Graphics issue could be due to you having duplicate kext in /E/C/k/Other and /L/E If they're not in the LE folder, you should keep them in /E/C/kexts/Other

See here, same patches used

replace AppleHDA_ALC292.kext with AppleHDA_ALC292.kext.zip to /Library/Extensions Repair permission and rebuild cache

Use bootpack here For keyboard key, see here

Follow instructions from here to debug issue gen_debug -sysprofile

1600x900 is fine too with DualLink

1080p has different video ribbon than the 1366x768. The 1080p has DualLink ribbon whereas SingleLink for the latter. Either replace the ribbon or get higher resolution display.

No issue with HDMI on my Haswell but mine is using port#5 0105. I had tried both MBA and MBP smBios without issue. Is your High Sierra install from a Distro?

add it right after it, don't remove it Give Bronxteck's suggestion a try

when you mount EFI partition, it should be right next to the EFI folder if not, then install Clover again, then time select under drivers64UEFI, check EmuVariableUEFI-64 to boot with -f, go to Clover Options. Next to boot, add -f after all the other boot arg or add it next to abm_firstpolldelay=16000 in the config file Not sure if it even works, but worth a try

try deleting Nvram.plist in /EFI. Reboot and let it create a new one. You could also try booting with -f arg
