How do I make the clock stop chiming every hour on the hour?

I'm using a fully updated 11.10 install. After I installed the gnome-shell 3.2 package the clock started chiming every hour (it sounds like a doorbell). If I'm listening to something that needs to be turned up loud...well you get the idea. It's annoying to say the least.

Disabling system sounds does NOT stop it. I can not find anything in gsettings or dconf/gconf-editor. Is there any one out there with a fix before I go crazy?

Solution 1:

It was not GNOME Shell at all. It is the timer applet 'Happytimer', which would explain why no one else has this problem. Honestly, it did not occur to me that a tea-timer applet would be this intrusive...then again, it's right there in the settings. I found the culprit by looking in the /usr/share/sounds directory.
