(HELP) No sound in Big Sur OpenCore

[OxTheLade]

So I have just done my first hackintosh on a Lenovo Thinkpad T440, but the audio is not working for some reason.
The output isn't even showing up at the audio settings.

Things I have tried:
Tried every layout codes
reinstall AppleAlc


The Specs are:
Model: Lenovo Thinkpad T440
GPU: Intel(R) HD Graphics Family
CPU: Intel(R) Core(TM) i5 4300U 1.90 GHz
Chipset: Intel(R) 8 series
Audio Codec: ALC 292
Network adapter: Intel(R) Dual Band Wireless AC 7260

I have attached my EFI folder down bellow.
Thank you in advance!

you should only have one <key> for your audio, with only one layout-id
