Cannot have audio output HP Probook 4540s

Hi. I have installed OpenCore 0.6.6 with OSX 10.15.7 follow Dortania's guide. Aida64 shown that my laptop's audio codec is IDT 92HD87B2/4, which has layout-id 12 in AppleALC Supported Codecs.

But when I set boot arg to alcid=12 in ProperTree, nothing happened. Mac show no output device. I have retried with different layout-id like 13, 3 but nothing seem to work.

Do you know how to fix this? Thank you.
