Problème son ...
Je ne parviens pas à utiliser le son sur mon portable HP nc6320.
Il s'agit d'une carte son intégrée :
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High
Definition Audio Controller (rev 01)
Le module est bien chargé : snd_hda_intel
J'ai placé ces informations sous /etc/modprobe.d/sound :
alias snd-card-0 snd-hda-intel
options snd-hda-intel model=hp position_fix=1 enable=yes
Le problème est le suivant : au dessus des touches f1, f2,... f12 se
trouve 3 touches. L'une active ou désactive le son, les deux autres
permettent d'augmenter le son ou de le baisser.
Celle qui "mute" le son est désactivée et allumée par une diode.
Je ne parviens pas ni manuellement, ni de façon applicative à
désactiver cette touche.
Le portable étant en dualboot avec windows. Sous windows, la
désactivation et la réactivation de la touche s'effectue sans problème
(manuellement et en utilisant le volume dans les propriétés audio).
J'ai essayé d'agir sur alsamixer et alsamixergui sans résultat.
J'ai essayé d'utiliser xmodmap avec le keycode 160 (information donnée
par xev) sans résultat.
J'ai utilisé alsaconf sans résultat.
Tout aide est la bienvenue.
Merci bien
Je tourne sous une Debian et sous environnement Gnome.
Je joints la sortie de amixer :
