Bonjour,

depuis quelques jours je galère pour configurer la sortie optique de ma carte son.
pour info je suis sous debian lenny beta 2 et j'avais déjà réussi à configurer le son, mais j'ai du réinstallé

J'ai un wav de test 5.1 qui dit 'front left, front right, etc', quand je le joue je n'ai que front left et front right donc du stéréo je pense

voici ma console
arecord -l

J'ai essayé de faire un alsaconf, situation identique

voici le fichier .asoundrc que j'ai récupéré de mon ancienne config, c'est ce fichier qui m'avais permis d'avoir le son 5.1

pcm.ch40dup {
    type route
    slave.pcm surround40
    slave.channels 4
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
}

pcm.ch51dup {

    ttable.0.4 0.5
    ttable.1.4 0.5
    ttable.0.5 0.5
    ttable.1.5 0.5
}

mais rien n'y fait.


Merci pour votre aide
