It happens to me sometimes with Plasma that the sound is a bit confused and I have to kill pulseaudio, after which it works, with Gnome it did not happen, I already tried to delete the various configuration files of pulseaudio, but the defect reoccurs … is there something that escapes me, and can I do something to avoid killing the pulseaudio process?
Can you elaborate a bit more about this issue? Otherwise we’re left to speculate.
I would like to be clearer, but the problem is random, the audio works fine but occasionally it has an annoying background noise, a rustle, which I solve only by killing pulseaudio, after which it resumes working well.
It’s not due to an unmuted microphone perhaps?
When it happens again, examine active sources…
pacmd list-sources|grep active
pacmd list source-outputs|grep active
amixer -c0
Just in case the following diagnostic guide is useful to you…

Yesterday I did some tests of stress, starting a video on youtube, and two tracks in my / home, but it went well, I closed everything and after a while I started a video on Youtube again and began to rustle, I took a screen

Well the amixer settings show the microphones off so I guess background noise is being introduced from some other unintentional “source”. I recommend using pavucontrol to check the configuration tab and make sure that the profile is set as expected, and that no unwanted input devices are set (or at least muted).
The problem is that it’s random, now I’m listening to music on youtube and it’s perfect, I’ve also enabled pulseaudio-equalizer and the sound is perfect, only that sometimes it starts to rustle and I have to kill pulseaudio 
Yes, it could be tedious to diagnose, but perhaps worth monitoring the output when pulseaudio is running from a terminal as described here…
The output of pulseaudio -vvvvv, run on the command line, is often helpful. To provide this correctly, first configure PulseAudio not to respawn itself automatically when it dies, by creating a file ~/.pulse/client.conf with this content:
autospawn = no
Then kill the existing server, with the command pulseaudio -k. Now launch pulseaudio -vvvvv from a console, and reproduce your problem. Provide the whole set of messages from the console where you ran pulseaudio.
Hopefully, when the problem next occurs while running pulseaudio like this you’ll be able to capture something meaningful.
Reference:
https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems#General_advice
I did not have time to read this answer that the problem occurred, I stopped the music video, I opened yast> sound> click on the sound card> edit> and I reconfigured the tab> restarted and no longer rustles, … … it seems that it loses the configuration, if it occurs again I feel like you said
Nothing to do I can not solve, after a while I’m listening to the music the sound deteriorates and you hear a rustle that disappears only after killing Pulseaudio, I tried the recommended solution, but it does not work 
Did you try the diagnostic approach (post #8) of running pulseaudio from a terminal to gather some output?
I’ve tried both when it works and when it starts to rustle, and the output is the same
I see now that the file created, last line, does not work

The output you posted suggests that you didn’t stop the pulseaudio daemon (as explained in the Fedora guide). The first setp is to disable autospawning…
The output of pulseaudio -vvvvv, run on the command line, is often helpful. To provide this correctly, first configure PulseAudio not to respawn itself automatically when it dies, by creating a file ~/.pulse/client.conf with this content: autospawn = no
The second step is to kill pulseaudio with
pulseaudio -k
then run pulseaudio from a terminal and monitor…
pulseaudio -vvvvv
Sorry but when I kill pulseaudio, even with the created file it regenerates immediately
Ok, do this
sudo setup-pulseaudio --disable
then run
pulseaudio -vvvvv
When you’re done with testing pulseaudio can be enabled to start automatically again…
sudo setup-pulseaudio --enable
BTW, the ‘setup-pulseaudio’ script writes to /etc/pulse/client.conf.d/50-system.conf, and when disabled the following entry is present
autospawn = no
When enabled…
autospawn = yes
It is set to autospawn = no and the output of pulseaudio -vvvvv is very long
It will be, and you may want to capture it to file for later analysis. For now I would leave it running via the terminal, and when you next get the “rustling” issue examine the output for clues (if any).
Mha, I do not want to talk too soon, but I installed Gstreamer Plugins and since yesterday the audio does not deteriorate and nothing more rustles, if it continues to work, then I also write the plugins I installed;)
Unfortunately pulseaudio does as it seems … assuming he is the problem, leaving pulseaudio disabled at boot and then starting it with pulseaudio -vvvvv always works well, without rustling
