Dear Everybody

My Build :
Open core 0.6.3 on OS 10.15.7 Catalina
Main Asrock Z490M ITX/ac
Cpu Intel i5 10400
iGPU UHD 630 (dGPU not Use)
Ram 32Gb,
SSD NVMe Samsung 970 Evo
Wifi MacbookAir 2012 BCM943224pciebt2

Full Working but there is only one small error:
Output the Audio to a monitor 4K screen(Phillip PHL 278E1) via a HDMI port and DisplayPort are both very well. But every reboot, the Audio output (PHL 278E1) is lost on the Speakers section of the Menubar. I must unplug the HDMI cable to re-plug it, this section to appear again. The same error goes for the Display Port.
How to fix this error, Thanks everyone.

Your post should probably go in Catalina support, not in desktop compatibility. More people are likely to see it there. If you have whatevergreen, and Apple ALC then it should just work. Have you checked to see if it is dropped in the sound system preference?
