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
load-module module-null-sink
we save the file with changes.

we should see null Output in the recording settings on the music card

Image

in the vlc program in the Audio tab - audio devices - null output

Image


we start alsa first
$ jackd -d alsa -p 4096 -n 4

Image


and run stereotool_gui_pi2

Image

in the input card default (ALSA) tab

Image

Image

Image

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.

You need to switch version of stereo tool from JACK to ALSA. Then set up chmod and run the stereotool. In the pavucontrol mixer there will be a recording tab and to record from the source "monitor of null output" it feels like this. It will show you on ubuntu but not ARM. Of course, music goes from VLC, exit from VLC to null output, recording stereotool from this source and exit from stereotool to any card you want.

and we don't need start alsa
$ jackd -d alsa -p 4096 -n 4

did you force the output usb sound card to 192khz?

I have it working like this, but no stereo and rds. I think its because of a wrong sample rate.
I put sample rate in stereotool to 192khz

i am using this as output card:

looks like its not running at 192khz:

hmm, i notice that my null output from vlc is mono. '
When i switch VLC to my normal output the stream is stereo. No idea where to fix that
edit:
sorry, my fault. Of course it is when i switch on 'encode stereo'

Hi,

I have a working version of Raspbian / StereoTool v9.52 available as a downloadable SD card image for a Pi3/Pi4 if you want to give it a try. File available here ... https://drive.google.com/file/d/1eC2E4g ... sp=sharing

And user guide available here ... https://drive.google.com/file/d/15GqlSb ... sp=sharing

It can run with either a live soundcard input or by using VLC as a playback device. This worked well for me last year, so even though the versions of both Raspbian and ST have been updated since then, it should still be fine today. Hope it helps.

Rodney.

Hi Rodney,

Really nice bit of software you have got there.

Can I ask some questions please:-

* where did you please the autostart of stereo tool?
* whenever you update the software using apt-get update then apt-get dist-upgrade it breaks everything?
* my mate is using the rpi 4b with 2Gb RAM it doesn't work on it it says please update software and fails to load up?

Any chance you could upset your image to meet the updated requirements of stereo tool, vlc and kernel please?

Many thanks

Richard Newberry
