Re-bonjour !
Suite à mon précédent post, voici les éléments de mon problème de carte son FireWire.
J’ai une Presonus Firebox, qui normalement fonctionne avec FFADO (elle est classée dans les “reported to work”). Toutefois, quand je la connecte, la LED reste rouge (elle est censée être bleue quand la carte est fonctionnelle).
Si je lance Jack, j’obtiens le message suivant :
12:43:45.329 JACK is starting...
12:43:45.329 /usr/bin/jackd -v -R -P80 -t2000 -m -dfirewire -dhw:0 -r88200 -p256 -n3

This usually means:
a) The device-node /dev/raw1394 doesn't exists because you don't have a
(recognized) firewire controller.
b) The modules needed aren't loaded. This is not in the scope of ffado but of
your distribution, so if you have a firewire controller that should be
supported and the modules aren't loaded, file a bug with your distributions
bug tracker.
c) You don't have permissions to access /dev/raw1394. 'ls -l /dev/raw1394'
shows the device-node with its permissions, make sure you belong to the
right group and the group is allowed to access the device.

Apparemment, le problème vient que ma carte n’est pas reconnue car je ne trouve pas de fichier " /dev/raw1394".
J’ai tenté la manip suivante :
code:/# lsmod | grep 1394
(none):/# modprobe raw1394
FATAL: Module raw1394 not found.[/code]
J’ai vérifié, le paquet “libraw1394-8” est bien installé, version 1.3.0-4.
De même, FFADO est bien installé. Si je lance “ffado-mixer”, j’obtiens le message : “Somehow the connection to the dbus-service of FFADO couldn’t be established. Sall we take another try ?”
J’ai écumé le web, j’ai trouvé quelques pistes mais rien qui corresponde à ma situation.
Comment peut-on vérifier si une carte FireWire est connectée ? Je dispose de plusieurs ports FireWire sur mon PC (un sur la carte-mère, que j’utilise par défaut, d’autres sur une carte PCI), cela ferait-il une différence ? J’ai tenté, rien ne se passe, mais je ne sais pas si ça fait une différence quelque part.
Merci de l’aide,
Nadelf
