Hi, thank you for the software! I'm trying to broadcast audio without latency. I was thinking about JACK to do that, but I can't pipe jack-stdout with pi_fm_adv because "Error: could not open stdin for audio input." Raspbian Stretch Any ideas ?

Hi, pifmadv expects a format supported by libsndfile. This includes WAV, FLAC, raw PCM and others. See http://www.mega-nerd.com/libsndfile/ I don't use JACK myself so I can't really help you.

try e.g. pi_fm_adv --srate 44100 --nochan 2 if your jack-stdout doesn't have headers.
