OcBinaryData VS AppleALC

HfsPlus.efi is missing, get that from this link and then put it in your Drivers folder: https://github.com/acidanthera/OcBinaryData/blob/master/Drivers/HfsPlus.efi

Fixed loading macOS with legacy boot without Apple Secure Boot: there is a new PE (Portable Executable) loader that broke legacy boot, blocking the loading of legacy drivers as HfsPlusLegacy and preventing OpenCore from booting on legacy systems when Apple Secure Boot is disabled. With this fix, legacy boot can work with or without Apple Secure Boot. This issue was detected after version 0.8.8 was released. While you are on 0.8.8, you must download the new versions of the drivers HfsPlusLegacy and ExFatDxeLegacy (the one/s that are necessary), available in Acidanthera. This is not required if you are on OpenCore 0.8.9.

Update Resources as well: https://github.com/acidanthera/OcBinaryData

Check if you have the latest resources Folder (included in OC Binary Data)

I'm able to download and open up the zip as instructed, but as far as dropping the "ExFatDxeLegacy.efi" file into the right location on my ESP (which I understand to be my boot drive, where OCLP was originally installed), I'm at a total loss.

Have you tried downloading the version from https://github.com/acidanthera/OcBinaryData ?

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
