Correct. Sorry about that. By the way, I looked at the github info for the audio library and it says it doesn’t work for single core devices (eg. esp32c3) but doesn’t say why. However, there is someone complaining about choppy audio and the answer seems to be that the tcp end of things is unable to fill the audio buffers fast enough. I intend to try it out as an mp3 player with an SD card to see if it can cope with that but I haven’t had time yet. Trying to get the esp32s3 to work at the moment. Let me know how you get on.
I have SCL connected to GND, BCK connected to D1. I’ll amend my original entry for anyone following this.
