[Jack, Rosegarden, qsynth]Avec clavier Maitre

[shom]

Salut a tous J'aurais besoin de vous car j'aimerais utiliser mon clavier maitre M-Audio Oxygen-49 pour m'éclater comme je faisais sous windows..
J'ai donc fait quelques recherches et j'ai installer Jack (avec qjackctl), Rosegarden et qsynth
Pour Jack : L'interface qjackctl n'arrive pas a lancer jack

J'ai donc essayer cette commande :

, je n'ai pas de message d'erreur, tout a l'air de bien fonctionner..

Je ne sais pas si le probleme vient de qsynth ou du serveur Jack.. J'avoue que je suis un peu paumé..
Et avec Rosegarden je n'ai aucun son..
Merci d'avance

Vois le wiki, JACK_Audio_Connection_Kit,

cannot lock down memory for jackd (Cannot allocate memory)

... car ceci semble indiquer que tu n'es pas dans le groupe audio.

[shom]

Pourtant

Code : Tout sélectionner

groups shom
lp wheel log video audio optical floppy storage scanner power users usbmux shom

..
Mais

Code : Tout sélectionner

ulimit -r -l
real-time priority              (-r) 65
max locked memory       (kbytes, -l) 40000

Et apparemment memory devrait etre "unlimited"
Etrange non ?

[shom]

J'ai éditer mon /etc/security/limits.conf et changer les valeurs comme ceci

Code : Tout sélectionner

@audio          -       rtprio          99
@audio          -       nice           -10
@audio          -       memlock         unlimited

et maintenant qjackctl semble se lancer sans probleme !
Mais maitnenant, lorsque je lance rosegarden, que je lui donne un fichier midi, et que j'appuie sur [lecture], il n'y a aucun son..
Et j'ai la meme chose pour qjackctl,j'ai bien le voyant qui me dit que je suis en train d'appuyer sur une touche. J'ai suivi ce qu'il y avait là http://forums.archlinux.fr/topic7600.html et là https://wiki.archlinux.org/index.php/USB_Midi_Keyboards
Et tout s'est déroulé sans probleme, aucun message d'erreur. Comment je pourrais tester jack a part ?
J'ai essayer mplayer -ao jack [nom_du_fichier] mais là encore, je n'ai aucun son, le probleme viendrait de jackd ?

[shom]

Comment je pourrais m'assurer que Jack marche sans probleme ? Et si il nemarche pas, comment le reparer ?
Merci d'avance

Et pourtant, jack fonctionne avec une autre carte son.. etrange non ? C'est possible qu'il y ait des problemes d'incompatibilité ?

[FoolEcho]

'sais pas... indique ta carte, voir.

C'est une Intel HDA (P7P55D) http://doc.ubuntu-fr.org/audio_intel_hda

'sais pas... (la documentation autour de jack n'est pas des plus étoffées... )

Jack ne (re)veut pas démarrer. Voilà ce qu'il me dit

Si tu supprimes ~/.jackdrc et relance jack ?

Au pif, tu as essayé avec jack2 ? https://wiki.archlinux.org/index.php/JA ... :_JACK2.29
