esp-adf VS ESP8266Audio

If you're getting started, the ESP8266Audio library makes it easy to play audio with the Arduino toolchain. For more advanced use cases, Espressif's own ESP-ADF has a lot of useful features and examples.

Take a look at the ESP-ADF recording example. https://github.com/espressif/esp-adf/tree/master/examples/recorder/pipeline_recording_to_sdcard

Sorry to break it to you, but the Korvo-2 is an ESP32-S3 based board and does not have classic Bluetooth (only Bluetooth LE). The a2dp+hfp example only works on the original ESP32 boards. See this table: https://github.com/espressif/esp-adf/tree/master/examples

I'm mainly looking for a direction toward a library that may assist in my project, or whether I need to do all this from scratch. Is esp-adf (https://github.com/espressif/esp-adf) something I should be looking at, is it relevant to the parts I'm using?

Example code https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_a2dp_sink_stream this is technically making a headphone with remote control but you can still use it as a starting point.

Espressif has an example for the esp32. I’m sure you could use it as a starting point to build what you need.

Having an issue here using the ESP8266 Audio library (found here).

The Arduino sketch that works for me reads the data out of PROGMEM. When I use that same raw data in ESPhome, it crashes my ESP too. Would there be a way to play from PROGMEM in ESPhome too? Other ways in the library are a function or streaming, but that doesn't fit my use case unfortunately.

Not sure where you got that. According to the ESP8266Audio documentation, the default GPIOs are 2, 15, and 3. You're trying to change 15 to 13.

ESP8266Audio is really fun and easy to use

The ESP32 might suffice for that then, depending on what you consider to be basic applications. It certainly has wifi and bluetooth functionality and you can do audio with an extra chip or an interesting workaround. The ESP32-A1S module even has the necessary chip integrated but you'll likely need to roll a custom PCB for it.

I am simply using the sample code from here. https://github.com/earlephilhower/ESP8266Audio
