Hello I have 1 question of am demodulation

Hello I have 1 question of am demodulation

 

I made simple AM modulation/Demodulation VI

 

that algorithm is

1.from sound input to modulation : (input signal * carrier signal) - top case structure

2.from modulated signal(sound file) to demodulation : (soundfile / carrier signal) - bottom case structure

 

now problem is in number 2 demodulated signal can't output any sound

 

when I divide after multiply in number 1 that worked

I'm wondering what am I missed

 

if anybody know that plz answer that
