Metronome/Sound

I have a question about the metronome. I have set everything in the menu, including playback, but I don’t hear any sound. The sounds on the pads work, just no metronome. I have the S2400 via USB on the computer and MixOut in Input SP 404 MK2, the output of the MK2 to my monitor speakers. I want to route both to Ableton and I have the S2400 on the IMac as sound output and input. What am I doing wrong? I love making music, but have never been the best at wiring.

Thanks and greetings Bohème

I have it. A new track with External Audio Effect in Ableton solved the problem.
