After updating to BigSur 11.5.1 there is no startup chime. I checked sound in system preferences and the box is checked requesting the chime sound to play at startup. Tried to uncheck the box and re-check it but it still does not work. Any suggestions?

If your sound is muted you hear no chime.

Reboot and try again.

Thanks for the suggestions. Tried it all, resetting NVRAM, SMC and Safe Boot.. Chime works when I use the power button but not when I use the auto start when the lid is opened.

To be honest I don't reboot that often and I don't pay attention to the finer details of the chimes going off.

You can call Call Customer Support  (800) MY–APPLE (800–692–7753)
