Sonoma 14.3.1 on X1C5 6300u - No audio

Hello,

I was able to install OpenCore on a X1C5 6300u with GMA 520. Everything appears to be working fine except Audio. It uses a CX11871 Audio Codec and other users have been able to get it to work with other variants of Opencore.

Here is my repo: https://github.com/anathonous/X1C5-Hackintosh-OpenCore-Sonoma/

and a repo of someone who got it to work.

Other repo: https://github.com/B0hrer/thinkpad-x1c5-hackintosh

How do I go about implementing in opencore? How do I patch it or point to the appropriate config?

Thanks
