Audio feedback is part of interactiveness between the OS and the user. this feature is missing in Linux Mint and so we have to go through the tedious job of installing Ubuntu Tweak, which doesn't work on Mate, to configure event sounds and input feedback sounds. I think it would only add to the elegance of the OS and give it a sense of completeness to have them preinstalled and preconfigured.
