ESP32-LyraT-Mini V1.2 as a voice assistant

Hello,

Does anyone have experience using the ESP32-LyraT-Mini from Espressif? I have recently purchased a couple, as the larger stereo version is out of stock.

This is my first ESPHome project, so I am a little overwhelmed. I have so far successfully connected the board and also gotten the onboard LEDs to work. But I cannot get the microphone to work. The board has an ES8311 codec for output and an ES7243 ADC for input.
