| 29 | A list of the connections between audio components. |
| 30 | Each entry is a pair of strings, the first being the connection's sink, |
| 31 | the second being the connection's source. Valid names for sources and |
| 32 | sinks are the pins (documented in the binding document), |
| 33 | and the jacks on the board. |
