Troubleshooiting jack (since 6 months ago)

I managed to set the proper buffer size and get rid of xruns, now everything works (or seems to work) with the exception that there is no listenable audio output, as for the machine, it enjoys the musioc instead of me hearing something. What I mean is that everything works like in a simulation because thereś no real soundwave coming at the lines, jack works smoothly with no errors, youtube videos play in browsesr and the metromer in pulse audio volume control swings at the sound on the playback tab under the jack sink, if I was deaf I would tell that audio is working with the exception that I hear the rain and no sound coming from the speaklers. I don't think that it's the incorrect output jack on the phisical line ()it could be though, but lets discard that for now because the same configuration works with standalone pulse, so the question is where is the sound dying?

I know that I should post a bunch of logs and dumps to help me detect whats falling but I really don't have the will nor the time to do it and also it's seeming now like a simple one obstacle problem now. Can you give me with this symptoms any hint on what could be failing?

Please post the Jack log.
Check that the audiograph is connected to the output device with qjackctl, carla or similar.
Try Pipewire.

As I say, everything seems normal for a non expert:

11:28:51.302 Reiniciar estadísticas.
11:28:51.303 Cambio en conexiones de ALSA.
11:28:51.304 D-BUS: Disponible (org.jackaudio.service aka jackdbus).
11:28:51.338 Cambio en conexiones JACK.
11:28:51.345 Cliente activado.
11:28:51.345 Patchbay desactivada.
Sat Mar 26 11:28:51 2022: New client 'qjackctl' with PID 39945

Server status: started
Samplerate 44100
buffer size 512

I changed idea about not showing logs, so please ask me.

There's also an annoying buzz I'm trying to remove that it comes at the sound peak when playing sound with pulseaudio, like a high pitched saw-tooth distortion.

my /etc/pulse/default/pulse.pa
