Signal Detection change source automatically

Hello Dave,

I need your support, I didn't find a solution yet:

- I would like to detect a signal input coming from the optical input and when it is true drive the Router Index to the corresponding source (in my case is Mix2)

- I tried to use the Signal Detection block, it can drive the GPIO but I don't find the way to select the Optical source internally into DSP

- I use the Router Index to change te source, maybe there is a better way to do it with Signal Detection or whatever

Thank you

Regards

Fabrizio
