Thanks for the quick response. Okay now I've connected my fireface's out to my voicelive's in (mono) and connected my fireface's out to my soundcards in (stereo).
I can see that the Voicelive 2 gets the signal from my soundcard, plenty of action in the little IN-meter in the bottom. I can also see that my soundcard receives the output from the Voicelive by my SIGNAL indicators in front.
No sound in ableton though. Tried "arming", putting it to in/auto on the monitor, but nothing.. Must be some settings? No signal in the ableton indicator. Maybe it's inside the TOTALmix software, no indication from 7/8 there as well (inputs i use)
Edit: nvm got it to work!
