J'ai essayé de lancer alsamixer comme indiqué :
root@debian-jb-amd:/home/jb# alsamixer
alsamixer: function snd_ctl_open failed for default: No such device
Echec, donc. Il y a bien nvmixer qui se lance, mais il ne propose aucun
réglalge particulier (si ce n'est le volume....), même en root.
Or il se trouve que j'ai remarqué les messages suivant :
jb@debian-jb-amd:~$ dmesg | tail -n 20
