Audio on Lenovo x1 yoga gen 2

[nukkaman]

I have had no luck getting the audio to work nor have I been able to manage a working copy of OC to transition to from clover. Any one that can help would be greatly appreciated. Currently I am using clover 5112 and Mojave. I want to retain touchscreen and pen capabilities when updating. Would like to get the system running Ventura.

I have moved your post to laptop support

best to enable these:

<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>
                <false/>
                <key>FixTMR</key>
                <false/>

this is very wrong:

<key>Audio</key>
        <dict>
            <key>Inject</key>
            <string>3, 15, 21, 23, 80</string>
        </dict>

you only use one number

I know. I forgot to change it back before posting. I’m my frustration I figured what the hell and tried it. I have everything now registering the right codec and test sound in clover menu is operational. However, no input or output devices are available when the OS loads.

are these required:

<key>AddProperties</key>
        <array>
            <dict>
                <key>Device</key>

                <false/>
                <key>Key</key>
                <string>layout-id</string>
                <key>Value</key>
                <data>AwAAAA==</data>
            </dict>
            <dict>
                <key>Device</key>
                <string>HDA</string>

                <data>b25ib2FyZC0xAA==</data>
            </dict>

as you already have this setup:

<key>PciRoot(0x0)/Pci(0x1F,0x3)</key>
            <dict>
                <key>AAPL,slot-name</key>
                <string>Internal@0,31,3</string>
                <key>device-id</key>
                <data>cKEAAA==</data>
                <key>device_type</key>
                <string>Audio device</string>
                <key>layout-id</key>
                <data>AwAAAA==</data>
                <key>model</key>
                <string>Sunrise Point-LP HD Audio</string>
            </dict>

have you confirmed that your audio device is PciRoot(0x0)/Pci(0x1F,0x3) ?
