J’ai fait une réinstallation de debian sur un autre disque dur, mais avec tout le reste du matériel. Silence total.

Speaker-test a l’air de fonctionner (mais silence total),
l’applet contrôleur de volume fait semblant de contrôler
(alors que si je désinstalle le module snd-hda-intel, il se pare d’une croix rouge du plus bel effet).
Bref : tout fonctionne parfaitement… à ceci près que je n’ai pas de son.
Si ça se trouve c’est tout bête, un câble débranché, allez savoir. J’y comprends que dalle.
