AKAI EIE PRO

Salut tout le monde,
il y a un développeur de chez ALSA qui semble vouloir regarder du coté de l'AKAI EIE PRO.

Pour ce faire, il a besoin d'information.

Donc si quelqu'un possède ce matériel, il nous faut les résultats de :

  • lsusb -v (pour confirmer)
  • lsusb -t
  • dmesg |tail (juste après avoir branché la carte son)

Hé les gens, y'a-t'il quelqu'un avec cette interface qui voudrait aider à la création des pilotes pour linux en donnant simplement les réponses aux commandes de mon premier message ?

Bonjour,
Je possède ce matériel, mais mes connaissances avec linux sont limitées.

J'ai eu un soucis avec le résultat de la première commande "trop long", puis j'ai découvert les redirections...

En bref, pour lsusb -v j'obtiens ceci :

J'espère que ça aidera.

Au besoin, j'ai le matériel en permanence chez moi, et après le boulot pas de soucis.

Super, merci Maxime.
J'ai fait suivre les informations aux développeurs d'ALSA, on verra bien ce que ça donnera. Ils ont une question : il semble qu'il y ait des ports USB supplémentaires sur l'interface (hub USB). Est-ce que ta ubuntu voit quelque chose si tu connectes une souris ou un disque dur ?
Si oui, pourrais-tu faire ce test : interface connectée, branche une souris sur le hub usb et file nous le résultat d'un "dmesg |tail".

Maxf12 utilisateur non connecté
Je viens de faire le test, et comme le confirme le résultat ci-dessous, le hub de la EIE PRO est bien fonctionnel.
Pour poster le message, j'utilise ma souris branchée dans un des port de l'interface...

Juste pour préciser, je ne sais pas si c'est normal, mais lsusb -v en redirection me renvoie ça :

maxime@Ubuntu-MAO:~$ lsusb -v > /home/maxime/sortie.txt

Donc il il y a le résultat dans le fichier et "Couldn't open device, some information will be missing" dans le terminal.

Super, je garde ceci sous le coude les développeurs ALSA.

ouhena utilisateur non connecté France
Les messages 'Couldn't open device, some information will be missing' sont normaux. Je ne saurai dire au juste à quoi ils sont dûs mais j' en ai aussi si je tape la commande. Une explication brève du pourquoi ils apparaissent dans la console: chaque processus, que ce soit une commande tapée en console ou un soft lancé depuis un clic sur une icône, se voit attaché 3 flux, un flux d' entrée, un flux de sortie standard et un flux de sortie d' erreur. La simple redirection avec '>' renvoie le contenu de la sortie standard vers un fichier. Comme les message 'Couldn't...' sont sur la sortie d' erreur qui n' a pas été redirigée, ils apparaissent dans le terminal. A priori tel que tu l' as fait c' est tout ce qui devrait intéresser le(s) développeur(s).

Loki Harfagr utilisateur non connecté
D'accord, d'accord, j'aurais dû regarder sur Linuxmao en premier lieu :-D)

Bref, je viens de mailer ceci ci-dessous à l'@mail de l'alsa-devel M-L,
au cas où ils le mettraient de côté ou que ça puisse servir en plus des efforts de Maxf12
je le colle aussi ici même et maintenant :

To test accordingly to the question a USB device (Webcam C905) is plugged in one of the EIE Pro. hub ports

Sincerely hoping it'll help to include full support in ALSA for the AKAI EIE Pro
as it's very good stuff, nicely built and convenient (for its hub) to USB ports
eaters as we're all in the music phylum :-)

Salut à tous...

Je viens voir de votre côté si des nouvelles sont arrivées au sujet de l'interface EIE PRO?

Une idée de l'état d'avancement?

Besoin de données supplémentaires?

Merci d'avnce...

A+

Max

Loki Harfagr utilisateur non connecté
il y a eu une progression dans les mise à jours jusqu'au 21 décembre (2014)
(et du coup je me suis simplifié quelques trucs en passant au noyau 3.18.1)

Des "trucs en plus" sont visibles et
"actifs" avec le driver en l'état mais comme il dit :
Image
The driver is by no means stable or ready to use.


Donc jusque là tout va bien et j'espère que le développeur va continuer mais ne
retiens pas tout de suite ta respiration car il doit avoir deux ou trois autres
trucs sur le buss en ce moment.

Maxf12 utilisateur non connecté
Bonjour,

Merci pour les infos.

Je me doute que ça ne se fera pas en quelques jours...

Mais on ne sait jamais, sur un malentendu (du style : "J'avais oublié que j'avais fini ça...")...

Bref, je continue avec mes fenêtres alors...

Merci encore.

Max

Je me permet de poster pour suivre l'avancement, parce que niveau caractéristiques cette carte son me plait vachement et comme je suis un mauvais en info et surtout sous linux, il me faut une carte plug and play.

Au passage merci aux développeurs, à ceux qui les aident et à toutes les bonnes volontés de ce forum.

Permets-toi, permets-toi boblebricoleur :-)
Si tu veux être mis au courant de tout nouveau message dans ce fil de discussion, regarde comment faire ici.

olinuxx utilisateur non connecté France
Maxf12, Loki Harfagr, vous avez des nouvelles des gens de chez ALSA ? Ça serait quand même dommage d'avoir les possesseurs de cartes ici, des développeurs motivés chez ALSA et que rien ne se passe :/

Loki Harfagr utilisateur non connecté
Non, aucune nouvelle hormis le fait que mon message de novembre 2014 avait été accepté par
le forum ALSA et qu'en décembre il y avait eu quelques évolutions (impliquant un saut de noyau)
mais je ne suis ni membre d'ALSA ou du kernel.org, ni membre de AKAI et si j'ai quelques
notions d'informatique/développement.système ou d'audio; et même, jusqu'il y a peu, quelque expertise sur certains points précis de ces divers mondes; bref
je ne peux ajouter la moindre information utile et n'ai aucun contact avec le ou les développeurs et de toute façon hormis des tests de compilation/utilisation/vérif ne pourrais faire mieux, s'ils ont besoin de bêta
ou alpha testeurs je peux souscrire mais n'ai (myopie plausible) vu aucune proposition en ce sens dans
le forum ALSA et al.

Maxf12 utilisateur non connecté
Rien de plus de mon côté, je continue de faire avec ce magnifique système stable et fiable vendu par défaut avec la plupart des machines.
Et je patiente tant bien que mal...

olinuxx utilisateur non connecté France
Super pour les réponses à vous deux.

@Loki, à mon avis, si tu causes un peu anglais, contacter le gaillard qui a déjà analysé le protocole et démarré de coder un pilote pour linux : http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/080905.html Image pourrait peut être l'aider à se motiver en se disant qu'il y a d'autres personnes intéressées et que des gens vont pouvoir l'aider à tester son truc.

@Maxf12, arf, tu m'en vois navré... je brûlerai une bougie pour soulager cette peine et aider à dévier les logiciels-espions et les trous de sécurité de cette machine. Puisse la force les empêcher de te nuire ! :-)

C'est bien cette même personne dont je causais, et il poursuit bien le développement mais il a d'autres devs sur le feu, la bonne nouvelle c'est qu'il y a 3 semaines il a posté (dans un "ticket de suivi") :

""
I do not recommend using the driver even for testing at the moment. It simply does not work correctly and has to be fixed.

I will try to look at it in the upcoming days. Stay tuned. I will close this issue and add some basic build/usage instructions to the readme when it is ready at least for testing. Thanks for your patience.
""

Ce qui en substance (avec le reste du contexte) se traduirait brièvement par "pour l'instant ne pas utiliser mais ça avance et je publierai des infos d'utilistaion/test quand ce sera publiable"

Donc, courage Maxf12, un jour tes souffrances finiront bien par être une vieille douleur oubliée ;-)
