Hi everyone, I am having an issue in studio one when using the 1824 interface. I want to setup outputs to send to performers, for example a singer. I have tried using the second headphone input but no signal comes through even though I have it routed to outputs 3/4 in studio one as stated on the manual. What is the proper way to setup outputs in studio one to be able to have a separate audio mix through the second headphone output?

Thanks,
Trent
