Intel NUC8I5BEH - No HDMI audio output -- rest working

Recently installed macOS big sur 11.2.3 with OpenCore 0.6.7 on Intel NUC8I5BEH following the guide https://dortania.github.io/OpenCore-Install-Guide/

Everything seems to be working fine other than the HDMI audio output (video working of course). I do get audio from the headphone jack and over bluetooth. And if I unplug the hdmi cable and replug it after boot up. The audio came out. This is very weird to me. People suggest using the kext fake_pciid. But I am not sure if this duplicates appalc. The codec on this NUC should be Realtek ALC233 and I have "alcid=28" set in boot-args.

Anybody has successful experience on this? Or where should I looked into to solve this problem.

Any help is much appreciated. Thanks!
