Bonjour,
Sur un ordinateur avec Ubuntu 18.04, le son ne fonctionne pas.
Après quelque recherche, j'ai donc vérifié dans le BIOS si la carte son est activée.
gnome m'indique que le son est mis en sortie fictive.
J'ai modifié les fichiers:
[*]//etc/default/grub [/*]
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 snd-intel-dspcfg.dsp_driver=1"
[*]/etc/modprobe.d/alsa-base.conf[/*]
options snd-hda-intel model=generic
Je ne sais plus quoi faire. 🙁
voici quelques informations:
