My 2 iMacs (macOS Catalina; Version 10.15.7) do not show a choice of "Play sound on startup" on the Sound Effects menu. On one iMac the opening crash chime sound is turned off. How do I turn it back on?
iMac 21.5″, macOS 10.15
On the iMac with no start up chime, run this command in the Terminal…
sudo nvram StartupMute=%00
If that doesn't work for some reason, reset NVRAM.

FWIW, the "Play sound on startup" setting was not available in Catalina.
