Hi, I have a presonus studio 1810c, but I can't get the second headphone output to work, at the output of the mixer in the studio one, it gives me a graphic signal, but I don't receive any sound signal from the second headphone output or when I enable the cue a / b button on the interface of Audio. I can't set the send level either. I have the drivers installed.
Cue B and headphone 2 is 3/4 line output in my audio interface, thanks in advance.
