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
* ROUT1
* ROUT2
* LINPUT1
* LINPUT2
* RINPUT1
* RINPUT2
* Mic PGA
Board connectors:
* Headphone
* Speaker
* Mic Jack
