    • Dell Latitude E6430: Carte du son ne marche plus sur LibraZiK 3

    Envoyé par mk1967 le Mercredi 22 juillet 2020 20:13 Allemagne
    Bonsoir à toutes et à tous 😎

    Sur mon Latitude E6430 j'ai un système multiboot: avec LibraZiK 3 (au passé: LibraZiK 1 et 2), AVLinux 2020, Win10 et Ubuntu 18.04.
    Sur LibraZiK 3 (et sur AVLinux 2020, qui est basé sur Debian 10 aussi) on ne peut plus entendre de son de la carte son intégrée.
    La carte continue de marcher sur Ubuntu 18.04.
    Elle marchait très bien sur LibraZiK 1 et 2.
    💡 Donc je suppose que c'est un problème avec le noyau de Debian 10.
    • Pour l'essai, j'ai demarré Audacious et choisi ALSA pour le truc audio (je suis désolé, je n'ai que des messages allemandes: "Ausgabe Plugin") et je lis "ALSA error: snd_pcm_open failed: connection refused."
    • JACK lui-même fonctionne bien: Je peux demarrer Ardour ou Audacious, je peux faire des connexions audio (et je peux voir qu'il y a du son là-bas, quand j'utilise EBUmeter par exemple), même avec la sortie de la carte son. Mais on n'entend rien.
    • J'ai ajouté un vieux appareil du son USB: l'Edirol UA-3FX. Avec cela, tout marche bien. 😬
    Quant à mon système:

    card0 est la carte que j'utilise normalement.

    Maintenant, je ne sais plus que faire... 😑

    S.v.p., auriez-vous une idée ?
    Si vous avez besoin de plus de détails, dites-le moi.

    Merci beaucoup d'avance 😊

    As-tu essayé avec différents noyaux (des noyaux lzk, et/ou des noyaux debian) ?

    Salut Olivier,

    j'ai essayé avec le noyau standard...

    J'ai regardé le menu GRUB2 mais je n'y peux plus trouver les noyaux LZK.

    Sur LibraZiK 3, je pourrais faire...
    Copy to clipboard
    sudo grub-install /dev/sda
sudo update-grub
sudo reboot

    ... afin que l'ordi demarre avec LibraZiK sur la position première.

    Je réfléchis si cela pourrait m'aider...?

    Supplement: En regardant la liste à Synaptic, je viens d'apprendre qu'aucun noyau LZK n'est installé 😬. Donc je l'essaierai d'abord... j'en raconterai.

    J'ai installé deux noyaux LZK-basse latence: 4.19 et 5.4.

    Après, j'ai ré-demarré l'ordi par Ubuntu 18.04 et fait un update-grub, mais le système n'a pas trouvé les noyaux LZK.

    Donc, j'ai ré-demarré LibraZiK 3 et fait comme ca:

    C'est curieux: le système ne trouve que ces noyaux amd64. 😬
    J'ai ré-demarré et je n'ai pu demarré que les noyaux amd64...

    En fait, j'aurais l'idée de ré-installer LZK 3 entièrement - mais (comme j'ai écrit) c'est le même problème avec la carte son sur AVLinux 2020. Donc je suppose que c'est un problème du noyau de Debian Buster...

    Malheureusement c'est le même problème avec la carte son sur ce noyau aussi... 😑

    Mmmm.

    Si tu en as la possibilité, je te conseille d'essayer avec une pure Debian 10 (buster).
    Si le problème est également là avec une debian buster pure, alors tu pourras utiliser les canaux d'aide Debian (BTS par exemple) pour demander de l'aide.

    Je suis sur la finition d'un bilan de formation en ce moment, alors c'est ma priorité et je n'ai pas beaucoup de temps pour aider à investiguer des problèmes complexes au niveau du noyau et du système.

    Tiens moi au courant.

    C'est difficile mais je réfléchirai - peut-être que je pourrai reinstaller l'entière distribution avec un Debian 10 d'abord.

    Mais: Je ne pense pas ❗ que c'est un problème de LibraZiK car j'ai le même problème avec AVLinux 2020.
    Donc peut-être que j'essaierai un forum pour Debian.

    Je te tiendrai au courant.
