Périphérique audio perdu après la mise à jour vers 18.10

Aujourd'hui, j'ai effectué une mise à niveau d'Ubuntu 18.04 LTS à 18.10. La mise à jour s'est exécutée sans message d'erreur. Après la mise à jour, les paramètres sonores indiquent simplement "sortie factice".

J'ai eu le même problème. Découvert sur n autre site que mon problème a été résolu en désinstallant timidity. Après un redémarrage, j'ai de nouveau le son.

Avoir le même problème et la recherche DNS aussi (sans presque aucune connexion Internet, il s'éteint de manière aléatoire toutes les premières minutes après le démarrage, situation assez ennuyante)
