The M1 mac laptops have gone partway in this direction, though they still have a great deal running as firmware: the speaker drivers can drive a lot of power into the speakers in order to get better and louder sound, but this opens up the possibility of a particularly aggressive waveform damaging the speakers from overheating. The OS is responsible for ensuring that this doesn't happen by modelling the power dissipated in the speakers and limiting the power when they are likely to be getting too hot.
