I looked at Settings->Appearance->Settings->Event Sounds
It is not checked.
I continue to get this rattle sound being played many times

I checked thunderbird, and it has all it's even notifiers unchecked.
Is there anything else to look at? I would really like to put a stop
to this (without having to mute the audio output).
