 * @brief  Demo how to use the microphone.
 * @version 0.1
 * @date 2024-11-03
 *
 * The microphone seems to be attached to 2 different i2s ports. In addition to the
 * ES8311, the ES7243 is also started. 
 * The I2S pins can be selected via cfg.i2s_function: CODEC uses the ES8311 I2S pins 
 * and CODEC_ADC uses the ES7243 I2S pins; By default the CODEC value is used.
 *
 * Only CODEC_ADC will give a proper microphone input!
