      A list of the connections between audio components. Each entry
      is a pair of strings, the first being the connection's sink, the second
      being the connection's source. Valid names could be power supplies,
      ES8328 pins, and the jacks on the board:

      Power supplies:
        * audio-amp

      ES8328 pins:
        * LOUT1
        * LOUT2

        * LINPUT1
        * LINPUT2
        * RINPUT1
        * RINPUT2
        * Mic PGA

      Board connectors:
