My USB 3.0 to VGA adapter arrived a few days ago so I tested the FM transmission example.
I used my own command for file playing:
$ ffmpeg -re -i sample.mp3 -c:v none -f wav - | pv -B 256k | sox -t raw -r 44100 -e signed-integer -L -b 16 -c 2 - -c 1 -e signed-integer -b 16 -t raw - biquad 4.76963 -2.98129 0 1 0.78833 0 sinc -15k loudness 5 | ./osmo-fl2k/build/src/fl2k_fm - -s 130e6 -c 350e5 -i 44100
And it really works! 🙂

Thanks it works great!
For now i want to transmit more than 1 fm stations. So that i can add a lot of internet radiostations to my fm radio.
That is possible because you can transfer a large fm spectrum. Do you have an example how i can do that?
Hi, I would suggest you to use https://wiki.gnuradio.org/index.php/Guided_Tutorial_GRC
How we can transmit on another station as if we change the carrier wave that makes no sense we need to change the fm transmission frequency but it ends up with an error
