Impossible de lire le son, erreurs ALSA lib
EDIT Ajouté ls -l/dev/snd /
EDIT Amixer ajouté -c 0
Je suis en train d'essayer d'obtenir mon serveur Ubuntu 12.04 lts pour jouer un fichier son. Cependant, j'obtiens toujours l'erreur suivante, indiquée par une commande test-haut-parleur.
UPDATE Je ne reçois plus l'erreur suivante, les fichiers son vont être lus (j'ai dû ajouter mon utilisateur au groupe son), mais aucun son ne peut être entendu.

Résolu en ajoutant mon utilisateur au groupe de sons.
Sudo useradd -G sound {username}
Puis j'ai forcé ma carte son intégrée à avoir un index de 1, donc la carte PCI par défaut à 0.
Trouvez la carte que vous ne voulez pas être le sourd. Le mien est snd_intel8x0. La valeur par défaut actuelle est l'index 0.
cat /proc/asound/modules
0 snd_cmipci
1 snd_intel8x0
Modifiez le fichier conf pour que la carte que vous ne voulez pas par défaut soit définie sur index 1
Sudo nano /etc/modprobe.d/alsa-base.conf
Trouvez la ligne:
# Prevent abnormal drivers from grabbing index 0
et ajoutez ce qui suit en dessous, en utilisant le nom de votre carte son à la place de mon snd_intel8x0
options snd_intel8x0 index=1
Enfin, redémarrez et utilisez alsamixer pour vous assurer que la carte n’est pas mise en sourdine.
alsamixer
Master Mono et Surround sont tous deux mis en sourdine. Si vous les basculez, cela devrait fonctionner correctement:
amixer -c 0 sset 'Master Mono' toggle
amixer -c 0 sset 'Master Surround' toggle
Si vous voulez changer le off en on, il vous suffit de répéter les mêmes commandes en utilisant le nom du périphérique.
Pour changer le volume, vous devez utiliser:
amixer -c 0 sset 'Master Mono' 100%
amixer -c 0 sset 'Master Surround' 100%
