kext VS AppleALC

do you have both USBToolBox.kext and UTBMap.kext? you need both USBToolBox.kext and UTBMap.kext for USBToolBox to function. https://github.com/USBToolBox/tool https://github.com/USBToolBox/kext

https://github.com/USBToolBox/toolhttps://github.com/USBToolBox/kext

Output from usb mapping is UTBMap.kext. Then you add USBToolbox.kext

If you have access to windows, this is a good usb mapping script. https://github.com/USBToolBox/kext. Heaps of guides around.

USBtoolbox, UTBmap

Do the usb mapping with USBToolboxadd Toolbox.kext too

Next, head here (https://github.com/USBToolBox/kext/releases)

Before you install OSX on the target machine, install Windows 10 or Windows 11 first. Make sure that ALL of your drivers for Windows 10 or 11 are installed (especially your chipset drivers). Use the Windows version of USBToolBox, and map your ports per their instructions (basic instructions are on the same page with the utility). Grab that here: https://github.com/USBToolBox/tool. Run the Windows.exe version (your antivirus software will go nuts trying to run this on your machine, either allow it, or rename the executable after unpacking it). Copy the created kext (called UTBMap.kext) file this program creates onto a separate flash drive to use after MacOSX is installed. Next, head here (https://github.com/USBToolBox/kext/releases), and grab the two kexts (USBToolBox.kext and UTBDefault.kext) within the zip file. Unpack, and put them in your EFI/OC/Kexts folder on your bootable USB drive. Use ProperTree to open the config.plist on your bootable drive, do an OC Clean Snapshot (this updates the config.plist with the new kexts you added), and SAVE.

Conexant CX20724 ISST Audio - AppleALC, , layout ID 13

https://github.com/acidanthera/AppleALC/wiki/Supported-codecs set alcid accordingly

I don't. Have you looked at the AppleALC wiki to see which IDs that might need? https://github.com/acidanthera/AppleALC/wiki/Supported-codecs

I have a Comet Lake laptop (i7-10510U & UHD 620) with the ALC294 Audio Card. I've tried all of the layout ID's listed on https://github.com/acidanthera/AppleALC/wiki/Supported-codecs. But all of them sound the same. I'm also using macOS Monterey... Any fix?

Do not enter the digits of your audio codec as your alcid. For example: "alcid=298" (ALC298). Use appropriate alcids from the AppleALC wiki: https://github.com/acidanthera/AppleALC/wiki/Supported-codecs

CPU: Intel Core i5-10500H (Comet Lake) [CPU slightly undervolted within BIOS] GPU: Intel UHD 630 (+ NVIDIA GeForce 1650 with Max-Q Design that's disabled via ACPI and boot-args) RAM: 12 GB Motherboard/Laptop Make and Model: MSI GF63 Thin 10SXCR Audio Codec: ALC223 Ethernet Card: RTL8111HS-CG Wifi/BT Card: Intel 802.11ax Wi-Fi 6 + Bluetooth v5.1 Touchpad and touch display devices: HID-Compliant Touchpad (Used VoodooI2C for touchpad) BIOS revision: -

Use linux to find out your audio codec (ALC...) and use this to narrow down the layout ids you could use. Try all of them and see which one works. Good luck!

So..i have a Lenovo Legion 7i Laptop with Realtek ALC287 audio codec, i've used layout-id 11 and 21, (21 seems to be better, since an internal and external mic device seems to be appearing on the System Preferences) however, although slider, volume, works...i still got no audio (both input and output), been surfing around and got to this link : https://github.com/acidanthera/AppleALC/wiki/Dumping-processing-coefficients
