The correct boot arg is alcid=
Maybe that's where you're going wrong. It could also be a different layout ID other than 1.

thank for your help.i understand that you say.my boot arg is alcid=7.i mean that when mac os reboot from win10. it no sound.i try to added alctsel=1.but no work.like this AppleALC not working from Windows reboot
If you find that rebooting from Windows into macOS breaks audio, we recommend adding alctsel=1 to boot-arg

I had the same problem yesterday , I kept debugging until early morning!.
I came across a post about uninstalling the windows Realtek driver and using the driver that comes with windows. Restart to MacOS sound is normal
