Bonjour

Je fiens d'installer fedora 25 sur un chromebook. Tout semble fonctionner sauf le son.
Voici ce que donne lspci
$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller (rev 0e)
Mais dans le logiciel "son" aucun logiciel n'apparait.

Quelqu'un a-t-il une idée ?
Bonne journée
Bonjour et merci de ta réponse,

J'obtiens
$ dmesg | grep audio

Bonjour et encore merci,

Je ne suis pas certain de savoir quoi faire avec ton lien. J'ai fait un dmsg voici les zones en rouges (une ligne en plus avant et après à chaque fois) :

Mais maintenant : quels firmware choisir et comment l'installer ?
Merci encore : j'ai vraiment l'impression d'abuser.
