I have an LG inverter microwave and it has an annoying "cute" song it plays when it finishes (and periodically to remind you unless you open the door). There seems to be no way to shut it up without opening it up and disconnecting things.

Have pulled open every microwave I've owned and cut the speaker. Dozens of buttons, not a single mute switch.

Microwaves are loud enough as it is, you can hear them running from the next room. Strangely enough never seen a toaster with an buzzer though.

This is why I genuinely feel like this stuff should be open sourced. There is no way that the firmware in a modern microwave is providing them some competitive advantage. Not everyone can recompile firmware but some helpful individual on a forum could dive in to it, provide an updated build, and share flashing instructions.

Manufacturers close source things by default but there’s so much improvements the hackers of the world could make to things if we had source code and schematics. I think it’s a real shame that the status quo is closed source by default.
