Lenovo ThinkPad E490 hardware details

There is a loud continuous sound from Lenovo ThinkPad E490 with FreeBSD 12.x-RELEASE almost every time booting up from a "reboot". 

This is probably better explained on https://forums.freebsd.org/threads/thinkpad-e490-sound-audio-only-works-after-specific-boot-from-poweroff-not-any-connected-plug.78286/

I experience the same problem on my Thinkpad E490 running FreeBSD 13.0-Release.
