* The 'loop1' gpio pin controlls two relays, which are either in loop
* position, meaning that input and output are directly connected, or
* they are in mixer position, meaning that the signal is passed through
* the 'Sum' mixer. Similarly for 'loop2'.
*
* In the above, the 'loop1' relays are inactive, thus feeding IN1 to the
* mixer (if 'add' is active) and feeding the mixer output to OUT1. The
* 'loop2' relays are active, short-cutting the TSE-850 from channel 2.
* IN1, IN2, OUT1 and OUT2 are TSE-850 connectors and DAC is the PCB name
* of the (filtered) output from the PCM5142 codec.
