GRC example of receiver cannot hear radio

I have installed gnu radio using ubuntu. I am using usrp2 with wbx
daughter board. I tried to test examples of grc “wfm_rx_pll”. This had a
usrp block instead of usrp2 so I replaced it with usrp2 block.

Decimation 128
Gain is 15dB
Frequency is 96.5M but I have a slider option.

I tried to run this file but all I can hear is noise rather radio
channel voice.

Regards,
Umer

Maybe the sample rates dont match up

Here is a youtube video of usrp2/Nseries FM radio. Maybe this will help:
