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 for sources and
|
|
|
|
|
sinks are the pins (documented in the binding document),
|
|
|
|
|
and the jacks on the board.
