I have just done clean install mojave 10.14.4. I couldn't get audio working. Things that I guaranteed:
- vanilla applehda.kext
- layout-id: 3 (via boot flag) (tried different layouts of ALC255 already, didn't work)
- all kext in /L/E (including AppleALC (debug ver), Lilu.kext, whatevergreen, codeccommander, ...)
- clean install (have not tried other fixing audio method)

Thank for your time. Much appreciated :)

in your config.plist, enable these:
Code: 
<key>Fixes</key>
            <dict>
                <key>Comment-IRQ Fix</key>
                <string>The following fixes may be needed for onboard audio/USB/etc</string>
                <key>FixHPET</key>
                <false/>
                <key>FixIPIC</key>
                <false/>
                <key>FixRTC</key>

Hi @Feartech
I am trying to complete my hack, but still can't get HDMI working. I got full QE/CI for HD4400 but when I plug HDMI cable in, both screen goes black and the system goes frozen. Could you give me some keywords to fix it?
i am using Whatevergreen + lilu (followed https://www.tonymacx86.com/threads/guide-intel-framebuffer-patching-using-whatevergreen.256490/) , default config for HD4400 laptop by rehabman, tried changing device-id & platformid didn't work.

Oh nevermind, I got it working by uncommenting all the framebuffer fixes. :D

kexts should be installed to /L/E not S/L/E

Hi, I also have just done clean install of Catalina 10.15.4. I couldn't get audio working. Things that I guaranteed:
- vanilla applehda.kext
- layout-id: 3 (via boot flag)
- all kext in EFI/CLOVER/kexts/other (since Catalina L/E and S/L/E is read only now) (including AppleALC, Lilu.kext, whatevergreen, codeccommander, ...)
- clean install (have not tried other fixing audio method)
-default s/l/e and l/e

I can't attach my reporting files because of Catalina I guess. So, I'll upload my EFI:

Thanks :)
