FIR Compller gives zero output

I have an input signal sampling frequency at fs = 44100 Hz (Mono Audio file). I use Xilinx FDA Block to do the low pass filter to filter out f>22050 Hz. FDA ==> Export cofficients to workspace as variable name "Num"

 

My settings

I worked around with papameters for a few hours but no good sign.

Make sure to run the simulation for a long enough time.

Also make sure that your variable Num is not set to all zeros.
