Solved:

The dev updated the theme (I am using Kripton https://github.com/EliverLara/Kripton)

So I want to get rid of these grey boxes that got added to everything in the overview. They are in the bar as shown in the image, they are in every text in the overview search as well.

For my taste it is disgustingly ugly. And I can't find where I can make it go back to normal.

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
