Help!!! Losing my mind over the AC-2 Acoustic Simulator

[Skullnick]

I finally finished Nabo's Acoustic Simulator and now it doesn't seem to give any sound. The volume control seems to be reacting. I checked the whole board a few times and everything seems to be allright but still nothing.
I will be very grateful for somebody's help.
