Super Meat Boy makes ear shattering sound with faudio.

[Bitwolfies]

Fire up the Windows port of the game (Not sure if the DLC makes a change but I do have it installed.) Wait for the announcer to stop speaking, and lower your volume immensely, its gonna be loud. Doesn't happen if xact is installed with Protontricks.

Tested version: Proton GE 55, with the install xact fix disabled.
