Hello. I have tried connecting my secondary laptop from the headphone jack to a line in channel on s4mk3, but I do not get any sound from my DJ speakers, so maybe I have a bad 3.5mm to rca splitter cord. However, if I do not have a bad cord which features on the controller and in preferences do I need to change/ setup? I tried input to channels c and d which are set at live input and selected line ext on the controller. It does not appear in preferences that my laptop is actually connected because this is what I see in preferences for input routing.
Thanks for guidance.
