Haut-parleurs non détectés ou ne jouant pas de son
J'ai une question similaire à celle ci-dessous, dont aucune ne résout mon problème:
J'ai ces haut-parleurs . Voici les résultats pour aplay -l et lspci | grep -i audio
:~$ aplay -l

J'ai essayé de supprimer et de réinstaller les pilotes:
# audio
Sudo apt-get install dkms
Sudo dpkg -i Downloads/...
Sudo apt-get install -f
# or remove / reinstall drivers
Sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
Sudo apt-get install linux-sound-base alsa-base alsa-utils
Sudo apt-get install gdm ubuntu-desktop
Sudo apt install pavucontrol
Rien ne fonctionne jusqu'à présent , toute aide serait la bienvenue. Les haut-parleurs produisent un son lorsqu'ils sont branchés sur mon ordinateur portable professionnel - un Macbook Pro-- donc je ne crois pas que ce soit un problème matériel.
