Missing HDMI-Audio NVIDIA

[UtterDisbelief]

you are only providing audio properties in your config.plist:

<key>DeviceProperties</key>
    <dict>
        <key>Add</key>
        <dict>
            <key>PciRoot(0x0)/Pci(0x1F,0x3)</key>
            <dict>
                <key>device-id</key>
                <data>cKEAAA==</data>
                <key>layout-id</key>
                <data>BwAAAA==</data>
            </dict>
        </dict>
        <key>Delete</key>
        <dict/>
    </dict>

you are missing your graphics in that section, be a good idea to check on:

Good point. There are two layout IDs in config.plist. One on command-line, the other in DeviceProperties.

(By the way I've edited my post above concerning MinKernel).
