Why can't I hear anything? please help!

Hey guys, new to the forum here first post. I just got Ableton and the first set I have saved is made up of 1 impulse w/hats, snares, and hits + 1 impulse w/just a kick + 1 analog channel for a sweep effect. For some reason, whenever I try to open the saved set, the only thing I can even hear is the analog. Both impulses show that they are playing, but I have no audio on them, and they are both turned on and don't appear to be muted or anything like that. Any suggestions are greatly appreciated and I look forward to my stay here.

Hi, enable In/Out preferences and look at where audio is going to from the impulse tracks?
