Signal coming in, not being passed through

Hey guys, hope you are well.

Today when we plugged our RCA cables from the pc into 47/48 ST we noticed that the sound isn’t coming through any of the auxes or the main mix. Signal is shown on the channel but when I turn up the fader to mix it in no audio comes through the monitors or the speakers. Could this be because of incorrect configuration? Pls let me know.

Most likely. Check the routing tab.

can you explain how I route it to the main and auxes?
