I fought for a long time to run stereotool the way I wanted. Not by jackd only stand alone, where you know what music card is on the input and what's on the output. Therefore I decided to do a tutorial for posterity: P how to run stereotool_gui_pi2 with vlc on raspberry pi3 with generated MPX and RDS.
We all know how to download and assign permissions for the program.
at the beginning we install pavucontrol.
$ sudo apt-get install pavucontrol
edit the default.pa file
$ sudo nano /etc/pulse/default.pa
we're looking for a ruler
# load-module module-null-sink
and we change to
we save the file with changes.
we should see null Output in the recording settings on the music card
in the vlc program in the Audio tab - audio devices - null output
we start alsa first
$ jackd -d alsa -p 4096 -n 4
and run stereotool_gui_pi2
in the input card default (ALSA) tab
and in FM Output a usb card.
I use REIYIN Audio usb 192khz and everything on it is MPX and RDS.

it is known that it is raspberry but still the quality of the whore is satisfactory considering quality 40%
of course, I run everything remotely via PUTTY or ssh.
