[Discuss-gnuradio] GFSK mod/demod does not work OK with wav file

[Fernando]

I'm playing with a GFSK modulator demodulator from here:

https://www.scribd.com/doc/254559988/Gaussian-Frequency-shift-Keying-With-GNU-Radio

It works fine when transmitting a cosine, but when I transmit a audio 
signal (everything the same) it sounds bad, with noise and intermittent 
sound.

What am I doing wrong?
