Monterey - Ivy Bridge - Realtek ALC892 audio

[lumin]

Hello,

I have followed this guide https://dortania.github.io/OpenCore-Install-Guide/config.plist/ivy-bridge.html#starting-point
and installed Monterey 12.7.3 OpenCore 0.98 on
Intel DH77KC, Intel® 82579V Gigabit, Realtek ALC892 audio
Intel i5-3570K Ivy Bridge
Intel® HD Graphics 4000 and AMD FirePro V4900 (not installed yet)

I am facing a few problems,
1. I cannot make Audio device Realtek ALC892 working, audio device is empty in info panel
2. Sleep does not work , I followed this guide https://dortania.github.io/OpenCore-Post-Install/universal/sleep.html
3. A mouse cursor sometimes freezes for 5-10 sec
4. I could find a good guide to install AMD V4900 card, best I have found - https://www.tonymacx86.com/threads/...00-is-not-supported-need-to-disable-it.74313/

Find EFI attached

Thank you in advance

you are listing your audio in both boot-args and also :

<key>PciRoot(0x0)/Pci(0x1b,0x0)</key>
            <dict>
                <key>layout-id</key>
                <data>
                AAAAAA==
                </data>
            </dict>

just use boot-args until you find the correct layout id first, reset nvram when you test each layout

For audio I deleted boot-args and use Device Properties, Audio is working,
I have temporary got RX 550 video card, followed some advice on internet and Video is working well now
