ALC221 on X99 (HP Z440) no devices

[Mackinaw]

Currently running Mac OS 10.14.6 on an HP Z440 and trying to get working ALC221 audio via AppleALC. I've read many people are using this same machine with working audio, but I'm not having as good luck.

I've had minimal success so far, though strangely, I thought I had gotten audio working fully yesterday (front and rear jack output came to life and were shown in Sound Preferences), but it stopped working on subsequent reboots, so it is definitely not consistent. The only consistently working audio I have is via HDMI.

So far I've tried various things such as:

• Clover patch for rename ALZA to HDEF (supposedly sometimes required for X99?)
• Install Lilu/AppleALC to L/E instead of CLOVER/kexts/Other
• Repairing permissions and rebuilding kext cache

A copy of my config.plist is attached, the same as what I'm currently using except SN/SmUUID/UUID changed.

I followed this to get Audio working on my z440 with SSDT-ALC221.aml, Lilu.kext, AppleALC.kext and CodecCommander.kext:

You then need to edit your config.plist in the devices section to look like this:

<key>Devices</key>
    <dict>
        <key>Audio</key>
        <dict>
            <key>Inject</key>
            <integer>0</integer>
        </dict>
        <key>Properties</key>
        <dict>
            <key>PciRoot(0)/Pci(0x1b,0)</key>
            <dict>
                <key>#Comment</key>
                <string>Realtek ALC221 Audio Configuration</string>
                <key>hda-gfx</key>
                <string>onboard-1</string>
                <key>layout-id</key>
                <integer>11</integer>
            </dict>
        </dict>
