Breaking changes in latest ESP32 Arduino Core

[SirSundays]

Hi,

a colleague and I are working through the Key Word Spotting Workshop and it took us a while to notice why it isn't working. Today we found that the Tutorial was most likely written on Arduino Release v2.0.14 or v2.0.17 based on ESP-IDF v4.4.6. The new Arduino Release v3.0.0 and later have breaking changes regarding I2S (First noted here: https://github.com/espressif/arduino-esp32/releases/tag/3.0.0-alpha1)

Getting the microphone to work on the new XIAO isn´t that straightforward but should be doable.

We are currently comparing the "old" implementation with the help of the old documentation (https://github.com/espressif/arduino-esp32/blob/idf-release/v4.4/docs/source/api/i2s.rst) to the new one. https://docs.espressif.com/projects/arduino-esp32/en/latest/api/i2s.html#arduino-esp32-i2s-api

There is also a "migration guide" (https://docs.espressif.com/projects/arduino-esp32/en/latest/migration_guides/2.x_to_3.0.html) Tho it doesn't really help migrating I2S.

Any help would be appreciated.

Regards
