Bonjour
Depuis quelques temps, j’ai un soucis. Sur DELL E7440, souci avec le son (sid à jour)
Si je branche le casque, pas de soucis j’ai du son, par contre, plus rien ne sort du PC sans casque sauf le son système
Le périphérique dans pavucontrol apparait toujours en unavailable
Voici quelques sorties, à priori aucun canal de muter dans alsamixer
