On the Adafruit ESP32-S2 Bugs and Limitations web page (https://learn.adafruit.com/adafruit-fun ... imitations) the following warning is present:
"No DAC-based audio output
Current versions of esp-idf do not have the required APIs for DAC-based audio output. Once a future version of esp-idf that adds it, it will be possible to implement DAC-based AudioOut in CircuitPython."
Since I am close to purchasing this device I was curious if this issue has been resolved by the
“Fix for mclk/bclk divisors #8326 (IDFGH-6698) #8327” at https://github.com/espressif/esp-idf/pull/8327?
If so, will this permit the Metro ESP32-S2 module to drive the MAX98357A amplifier using the I2S interface?

It looks like the ESP-IDF v4.2 (Dec. 2020) added i2s support.
