Cant hear Audio playback in M.C. Pro24

I have an electric guitar plugged into a 6 track soundboard. This is going out left into the input left jack on the pigtail of my Audiophile 192 sound card. My sound cards mixer recognizes the guitar and shows its signal, as does the clip meter in calkwalk. When i record it records fine and it shows up on the track. However when i play the playback, i dont hear any sound
 
Im pretty new at this. Any Help?
