+ * 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.
+ *
+ * Unfortunatly neither setting will give a proper microphone input!
