It seems sound is only not working through the internal speakers but working with all other external devices that I plug in/bluetooth

Ah okay thanks for clearing that up! The only change I made was use my own SSDT which I generated, could this possibly have any effect? Also, could I move the relevant kexts to either S/L/E or L/E and give that a shot?

Ive just done a fresh install using Herves guide, using a new installer and brand new installation file from the AppStore and I still unfortunately dont have sound, is there anything else I can do to debug? IIRC when I had installed sierra a few years back I had to use a the patched AppleHDA and was wondering if theres anything similar I might need to do here

No luck using your config.plist and kexts, everything still boots fine but sound don't work unfortunately Does the nvram.plist have any effect on this? I do see some settings relating to sound in there (SystemAudioVolume set to YA== and SystemAudioVolumeDB set to YA==) Sorry I should also mention that I am dual booting with windows and sound is working fine there

@Jake Lo Testing with the internal system settings sound preferences and also by playing videos etc @Hervé Will try this again and update!

Hi, I recently upgraded my E6220 with i7-2620M from Sierra to High Sierra (as a fresh install on APFS). I followed both Herve's and Jake Lo's installation guides for the E6220 but I am having issues getting the audio to work. I have tried using different and the latest versions of Lilu and AppleALC but have had no luck. I am using Herves DSDT file (from here) with my own generated SDST and currently a combination of both Herves and Jake Lo's config.plist as I had issues with the integrated webcam which is now working (bear in mind even using the original config.plist from both guides separately audio was not working). Surprisingly the microphone is working and the audio switcher is working and not disabled. Does anyone have any ideas I could try? Or maybe a full reinstall is needed? Thanks. config.zip

Still no luck unfortunately Ill give this a shot, do I need to replace just the ssdt and dsdt.aml files for my i7 processor?

Right after mac os installation, so its just about to finish installing, the message comes up. I select the installed drive and I get a 'boot0af: error' EDIT: picture of where the message appears: http://i.imgur.com/xA1kDA3.jpg

Model: Dell E6220 i7-2620m, 8GB ram, Intel HD 3000 I'm currently following pafkata's guide on running sierra on my e6220 using clover: https://osxlatitude.com/index.php?/topic/9383-dell-e6220-i7-2620m-clover-detailed-guide/ Everything works until the very end of the macOS installer where I get the error "building boot caches on boot helper partition failed". I have tried booting into the SSD anyway but get a boot0af error. Does anyone know how I can resolve this issue? (P.S this is the first time installing Mac on this laptop) Thank you.
