I send system bleeps and beeps through it, that's all. Virtually no effort was put into making its sound decent, because the Studio (and the Mini) are not marketed as a complete package, unlike every other Mac. You are expected to use these computers connected to another device with better speakers. In Apple's ecosystem that other device would be the Studio Display, which to be fair, sounds pretty good for what it is. But still, and on the other hand, the mediocrity of the Studio built-in speaker is shocking in 2023 for a >=2K computer.
