HP Elitebook 840G5 - Opencore - No Audio

HP Elitebook 840G5 - <a class='btn btn-link py-0' href='/p/opencore.html?id' target='_blank'>OpenCore</a> - No Audio

Hi everyone,

I'm fully new on reddit and Hackintosh. I'm trying to fix the audio problem with this hackintoch.

I followed the OpenCore Vanilla Guide to make this hackintoch and I'm actually here Fixing Audio.

Audio Codec : CX8200 / Layout-id : 23

gfxutil -f HDEF : 00:1f.3 8086:9d71 /PCI0@0/HDEF@1F,3 = PciRoot(0x0)/Pci(0x1F,0x3)

I have sound if my boot args are alcid=23 but I can't get it when I go back to alcid=xxx and set the DeviceProperties like this:

config.plist

Any ideas of what am I doing wrong ?
