Ableton Forum

Hi. I have an E-MU 0404 USB soundcard and have a problem. In Input/ouput settings in Ableton i have 1/2, 3/4 stereo. So I set 3/4 for cue but in my headphones i have such waves as in my monitors(they are install in headphones out) which are seting on 1/2. But in Tractor for example ied see 3/4 channels as s/pdif out. So I must install my headphones on s/pdif-output? And is this possible about passive headphones to install there into s/pdif-output?

thnx for yours answers
