1. don't play games at Pogo.com!
Ok, not a solution. Could it be that you are resting something on the keyboard and you are getting the "repetitive key" alarm?
Does the sound go away when you got to another site, away from pogo.com?
I'm using a PowerBookG4. OS X, Version 10.3.9
I get this annoying sound when I'm on the pogo.com website playing games. All the normal game sounds are fine and then all of a sudden I get this "pinging-dinging" type sound. It doesn't stop. I have to mute the sound on my laptop.
Do I have some kind of alarm set that I'm not aware of? It'll only stop when I shut down Safari.
I'm a realively new Mac user, a little over a year, I love my mac, and this is the only annoying problem I've found.
