Salut,
Non, je n'ai créé aucun fichier pour configurer ma carte audio.
J'ai suivi ta dernière indication, ce matin j'ai reconfiguré la carte audio (car bien sûr elle était désactivée) puis activé pulseaudio.
Redémarré l'ordi (avec de nouveau l'icône audio grisée) et en console les commandes :
pacmd list-sinks | egrep 'index|name:|muted|device.description|active'
* index: 0
name: <auto_null>
muted: yes
device.description = "Sortie factice"
jean-luc@Host-001:~> pacmd list-sinks
1 sink(s) available.

Résultat pas surprenant puisque la carte audio est désactivée.
Si je la reconfigure et vais tout de suite faire les commandes (sans redémarrer l'ordi), bien sûr le résultat est différent.

Faut trouver la raison pourquoi le fait d'éteindre l'ordi annule la configuration de cette carte audio !!
