Bonjour,
Je n’ai plus de son via la carte de l’ordi, et le périphérique physique n’apparaît plus, en entrée comme en sortie.
Au boot, je trouve dans les logs :
snd_hda_intel 0000:00:1b.0: no codecs found!
Un peu plus d’info sur ce périphérique…

La machine : un Dell Precision M4800
l’OS : Debian stable.
Je précise que tout fonctionnait bien avant.
Je soupçonne une panne matérielle ou une désactivation, mais je ne sais pas déchiffrer la sortie de lspci.
