You appear to be using the sink_input_index value before you even run
the main loop... This value will just contain the default values and
thus I suspect they all have 0's which ultimately maps to the default
monitor source and no specific sink input.
You need to run the main loop and let all the necessary call backs be
called and get all the necessary index values before you actually use them.
