Hello, I am trying to use FM transmitter for wav file as well as for audio source.  
With wav file I am able to receive at other end on selected band. But when I try to replace wav file source to audio source nothing happens, USRP\_b205 mini doesn’t receive anything.

I also tried external sound card and given device name the id of the sound card, but still no issue.

I would appreciate the help
