arecord and aplay both work fine on the hardware (1st gen AIY on pi 3B+) for record and playback. I’ve tried on both a current Raspbian image with the AIY drivers added and with the AIY image from 2021 (last available one), no difference.

aplay -l

which looks fine I believe. arecord is the same. playback outside Rhasspy is fine.
