Lenovo G50-70 - no audio on Big Sur with AppleALC

[Graaanityy]

Hello guys,

since I Hackintosh'ed my GA-Z87-D3HP successfully with Big Sur, I decided to install Big Sur on my Lenovo G50-70 laptop.

Specs are:
CPU: Intel Core i7 4510U
GPU: Intel HD4400 & AMD Radeon R5 M230 (deactivated with -wegnoegpu)
HDD: Seagate 500GB SSHD
RAM: 8GB 1600MHz
Ethernet: Realtek RTL8111 family
WiFi: Qualcomm Atheros AR9565 (working with AirPortItlwm.kext)
Audio: Conexant CX20751/52



I got everything working, except audio over AppleALC.kext.

On my other build, AppleALC is working fine.

If I'm using terminal with kextstat -n, AppleALC seems to be loaded. But in Settings->Sound->Output there are no devices.


Also Hackintool isn't showing anything.

What I tried:

- using -alcdelay=1000
- using alcid=3, 21, 28 like it's shown in AppleALC's supported table list
- using FixHPET in SSDTTime
- using PciRoot under DeviceProperties->Add->PciRoot->layout-id
- using a patched AppleHDA (removed AppleALC before) but just crashed the whole system


I attached my EFI folder.

I attached my EFI folder.

your device properties is only showing your Graphics, missing your audio properties:

Why do I have to add it to DeviceProperties? I added alcid=3 to my boot flags.

I had the same issue until i added to DeviceProperties

What do I have to add unter PciRoot in DeviceProperties? layout-id and device-id?

hackintool can create this for you, check the link above

The problem is, that Hackintool isn't showing anything under Sound...
AppleALC is installed under EFI/OC/Kexts

it probably won't without something like:

<key>PciRoot(0)/Pci(0x1f,3)</key>
            <dict>
                <key>layout-id</key>
                <integer>3</integer>
                <key>hda-gfx</key>
                <string>onboard-1</string>
            </dict>

I don't know if I'm just a noob or AppleALC has no support for Big Sur?
Can you please tell me in steps what I have to do?

Hackintool isn't showing anything under Sound and from where do I know what I have to add to DeviceProperties?

AppleALC works fine on Big Sur

you will need to add the above to your config.plist and change the layout id number (currently it is set to 3) as per:

Supported codecs
