    No playback with MuseScore 4

    Hello. (Excuse my english, I'm french.)
    I use Kubuntu 23.04
    I have a permanent problem: MuseScore 4.* (MS4) seems to conflict with any other software that produces sound.
    Description: I launch MS4, I play a score, everything is OK. I stop the score. I try to listen to music on Rhythmbox, VLC, or other: impossible. I have to close MS4, and restart Rhythmbox (or whatever), and restart MS4 for it to work.
    The opposite is true: if I start by listening on Rhythmbox (or other), impossible to play a score in MS4, I have to stop Rhythmbox, and restart MS4.
    Looks like MS4 refuses to share the sound card with another program.
    But I don't know how to fix this.

    Has anyone had the same problem? Never had this problem neither with MuseScore 3.* (MS3) nor with other sofwares.

    ​Last precision : I have this problem since the beginning of MS4, 6 months ago. I tried with each version, even nightly builds.
    Not having found a solution, I dropped MS4, and I continued to use MS3. I ended up telling myself that by tweaking my machine, I had done things that were incompatible with MS4.
    But 3 days ago I reinstalled everything, from scratch, and without leftovers from the previous install.
    Well, it's always the same: impossible to play a score if another app is producing sound. And impossible for other apps to produce sound if MS4 is playing a score. :-( :-( :-(
    Am I really the only one this is happening to? It's probably nice to be "exceptional", but this is giving me away!! ;-)​

    I launched MS4 from command line. Here are the output. I hope it will help.
    Thank you in advance.

    I answer to my self...

    Hope...

    I killed almost every app on my computer.
    I run MS4 on a pre-existing score, it plays it with no problem.
    I then run VLC on a fairly basic MP3. VLC refuses to produce sound (as usual), BUT VLC displays this message in the command line:
    Code:
    [000055a7b227d400] pulse audio output error: overflow, flushing
    I look on the web for what it is. Nothing for me.
    But I see that there is a "pulseaudio" command which is not installed on my machine. I install it and I run it.
    And it works, everything can play at the same time, including MS4!!!!!!!!!!!!!!!!!!!

    Now I will have to understand the difference between this command and the pulseaudio which was already installed (necessarily installed, since pulse audio output error).
    And I will have to understand how to launch it automatically (that's not complicated).

    I replace a riddle with another riddle, but in any case it works.
