Folks, why would they even change it to whatever that new hum is. It sounds all like BEhWOE BEhWOE BEhWOE, the old one felt like spamming menu options in gta4.

Where is the old hum sound? WHere is that mp3? how do i slap that into the settings menu? I wish this was sarcastic.

Edit: Ok so its gonna be an .ogg file to go in "/usr/share/sounds/gnome/default/alerts/" , just need the old hum sound file

Edit 2: For anyone like myself, I found it here
