I am trying to broadcast audio from my raspberry pi with pifm. However, it isn't working.
When I run 'sudo ./pifm sound.wav 100.0' nothing comes through on my fm radio, and also, afer about 2 or 3 seconds the terminal says 'exiting', and exits.
The same happens when I run 'sox -t mp3 ribo.mp3 -t wav -r 22050 -c 1 - | sudo ./pifm - 100.1'.
What can I do to fix it?
