Vc = vertical
Hc = horizontal

Shouldn't make a difference in terms of getting sound out. Haven't played with the config program for a while so can't offer much more! Have you tried changing the DSP preset? Trifield would definitely give an output.
When you say you have it daisy chained do you just mean comms because the centre audio feed will need to come from the processor.
