Connecté avec succès à un haut-parleur Bluetooth, mais comment puis-je diriger le son là-bas?
J'utilise Kubuntu 13.10 sur un ordinateur portable Lenovo Thinkpad T430.
J'ai un haut-parleur Bluetooth.
Après beaucoup de dépannage, j'ai réussi à me connecter au haut-parleur. bt-device signale:
$ bt-device -l

[Samsung] W_Audio (5C:F6:DC:88:05:62)
$ bt-device -i 5C:F6:DC:88:05:62

Lorsque je me connecte au haut-parleur, il émet un son de bienvenue. Lorsque je clique sur "Audio Sink" dans le gestionnaire Bluetooth (c'est BlueMon, je pense), le haut-parleur émet un autre son et un message "Success" apparaît dans le gestionnaire Bluetooth.
Mais l'audio bluetooth n'apparaît nulle part dans les paramètres. Il n'y a pas d'option pour diriger le son vers le haut-parleur. Tout le son provient des haut-parleurs d'un ordinateur portable et le haut-parleur Bluetooth est silencieux.
J'ai installé pulseaudio et pavucontrol (avec un tas d'autres paquets liés à pulseaudio et bluetooth). Pavucontrol sur l'onglet Périphériques de sortie affiche uniquement le périphérique audio principal, mais selon les guides du Web, le son Bluetooth devrait y figurer.
Alors ... Une fois le haut-parleur bluetooth connecté, comment puis-je diriger le son là-bas?
Quelques décharges qui pourraient être pertinentes:

Pour activer la découverte de périphérique audio Bluetooth dans Pulse Audio, nous devons nous assurer que nous avons bien chargé les packages Bluetooth pour pulseaudio ( pulseaudio-module-bluetooth) devrait être installé par défaut).
Le module -bluetooth-discover est ensuite chargé d’ajouter un périphérique audio Bluetooth comme récepteur (ou source en mode HSP/Téléphonie) aux périphériques audio connus.
Pour charger ce module, nous pouvons émettre
pactl load-module module-bluetooth-discover
Pour toujours charger ce module au démarrage du serveur de son pulseaudio, nous ajoutons les lignes suivantes à notre /etc/Pulse/default.pa (ou à notre ~/.Pulse/default.pa personnalisé, ou ~/.config/Pulse/default.pa resp., Si ce fichier existe):
### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif
J'ai eu le même problème. Sur https://wiki.archlinux.org/index.php/Bluetooth_headset J'ai trouvé ceci:
Remarque: le périphérique peut être désactivé par défaut. Sélectionnez son profil audio (OFF, A2DP, HFP) dans l'onglet "Configuration" de pavucontrol.
Après avoir sélectionné A2DP, il y avait du son.
