AppleALC VS SSDTTime

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

Build SSDT-EC, SSDT-USBX, SSDT-XOSI, SSDT-PLUG, and SSDT-HPET from SSDTTime instead of manually https://github.com/corpnewt/SSDTTime

I'm trying to do a fresh install of Ventura. I tried using SSDTTime from my Catalina at first, only to discover that the option to dump DSDT is disabled by design because that'll not give me the unadulterated DSDT which makes sense.

Precisely, I went through the guide once more, discovered some new tools (like USBToolBox for example) then I did USB mapping + SSDTs (using SSDTTime) by hand (I was not sure that I did them properly in the first place, 3 years ago). Then with those clean SSDTs & kext, I used my old EFI and OCAT to merge everything together. Double checked everything at the end just to be sure that I did not forget a thing and that OCAT did not mess up anything.

I couldn't get past this point in mine without running https://github.com/corpnewt/SSDTTime and enabling `SetupVirtualMap` in Booter Quirks

It's a must though. Every PC is different, even 2 identical models might not have the same ACPI tables.. I would Start here.. There's only a few things you'll really need, especially on these machines. While there's many methods, a clean install of windows NOT booted through OpenCore, using SSDTime is the easiest for most.

I built my own SSDTs using SSDTTime.

OpenCore 0.8.7 / Dumping DSDT use SSDTTime for generate ACPI Tables / Use genSMBIOS for generate MLB (Board Serial), ROM (Mac Address), SystemSerialNumber (Serial), SystemUUID (SmUUID)

try mapping usb drive on windows first using USBToolBox as USBInjectAll isn't fully working anymore on Monterey. Also I suggest creating your own SSDT/acpi patches via SSDTTime.

If so, switch back to AppleALC and add SSDT-HPET.aml with the patches in the patches.plist generated in SSDTTime (https://github.com/corpnewt/SSDTTime).
