Hi, sorry I couldn’t respond sooner. Basically everything is in this thread except that I was using this:
https://github.com/schreibfaul1/ESP32-audioI2S
As I said previously, on a C3 chip it is choppy at the speed most internet radio stations stream but at a lower bit rate it can cope. The one issue I did come across (and its a while since I did anything with this) that Adafruit provided an “Audio” routine as part of their development pack and although it says its only for a specific device type the internal parameter settings said it was for all device types and Arduino IDE was selecting that instead.
If its any consolation the S3 version works just fine but you must use the correct pins - also documented elsewhere in this thread.
Best of luck.
