taking big DONG sound at start up mac osx catalina

Hi

I once got rid of that sound by having headsets and it worked but I forgot how


yesterday I took the headsets off, then put them back big dong is back


I tried everything, music comes out of the sets but If the light on the sets stays after turn off

all would be good but they don't they shut off too


or is there a way to shut all sounds off and turn on only when I listen to music?


I had a trick and lost it - plz any one I would be grateful


tks

You can silence the chime in Catalina without having to use the mute key.


Open Terminal in the /Applications/Utilities/ folder.


To disable the Mac startup chime, copy/paste this command into the Terminal window:


sudo nvram StartupMute=%01


Press enter and provide your admin password if asked.


To re-enable the Mac startup chime, copy/paste this command.


sudo nvram StartupMute=%00
