Platform not found: "adf_pipeline.i2s_audio"

I have been trying to set up a voice assistant including a media_player using this library, very happy to find this work (thanks!) as we've come to rely on announcements from the Google Mini I am trying to get rid of.

I have tried to implement this on several boards, home-made ESP32 and, after giving up on that, an m5stack-atom. The issue is, even when directly copying code from examples found here, errors state the platforms won't load up.

I must be missing something obvious.. thanks in advance for any help

ESPHome (container, esphome/esphome:latest) web console displays red lines from '- platform: i2s_audio' below "adf_pipeline:"
Error reported: 'Platform not found: "adf_pipeline.i2s_audio"'
Have tried cleaning build files, even deleting the esphome config and reinitialising the container
Example yaml (https://github.com/gnumpi/esphome_audio/blob/main/examples/m5stack-atom-echo-adf.yaml) as follows:
Only modification made was for wifi (i.e. #### Only change START/STOP)
