Si je ne démarre aucun flux audio je n'ai pas ces messages, mais dès que je démarre, par exemple, vlc ces messages commencent à remplir mon /var.
J'ai fait un autre essai
boot
Pas de vlc ni de flux audio.
Démarrage virtuabox (avec son sur pulseaudio)
Même chose et dès le démarrage de la machine virtuelle et pas lors du premier son émis par celle-ci (musique du démarrage terminé).
