pas de sons: sortie fictive

bonjour à toutes et tous
aujourd’hui, pour résoudre un probléme avec thunderbird,j'ai bidouillé avec timeshift, j'ai restaurer un snap vieux de plusieurs mois, puis un autre, puis une derniere fois un snap, vieux de 24H
resultat des courses, j'ai réparé thunderbird, d'une autre maniere, mais au passage, est apparu le célèbrevoul probléme de la sortie fictive
hier soir elle fonctionnait tres bien
dans pluse audio, en peripherique de sortie j'ai "sortie fictive", dans configuration , je n'ais rien
un "inxi -Fxxz" me donne ça
