If for some reason my code exits without calling I2S.deinit(), after I soft-reboot the board (crtl-D in REPL) I get the following message:

ValueError: I2S port is already in use

Apart from a hard reboot (unplugging and replugging my USB cable), is there a more elegant way to deinit() I2S?

You could reset the ESP32 in the REPL. That might be a better method compared to unplugging/plugging the USB cable?

import machine
machine.reset()

Workaround provided.

The latest commit removes the need for a hard reset.
