If you'd like to make an audio project with I2S there is a new PR and updated code in I2S examples repo to support the Pico.

The firmware on your Pico board will need to be updated. There are a couple of options to get firmware:

1. Integrate the I2S PR into your local build
2. Use a firmware binary from the examples repo.

Most of the examples require a SD card. The Pico board does not have a built-in SD card slot so an external SD card module will be needed. Also, the Pico firmware does not have native SD card support, so the Micropython SD card driver needs to be copied into the Pico internal filesystem using a tool such as rshell or ampy.
