Les touches multimédias ne fonctionnent pas

Mes touches de sourdine, d'abaissement du volume et d'augmentation du volume fonctionnent, mais pas les touches mon précédent, suivant et lecture/pause.

J'ai essayé la solution postée ici , mais cela ne semble pas être le problème. Tous mes paramètres org.gnome.settings-daemon.plugins.media-keys semblent être préfixés de manière appropriée par XF86:

Voici le résultat de l'appui sur précédent, suivant, lecture/pause et muet dans l'ordre:

J'ai décidé d'examiner cela un peu plus. Apparemment, si vous avez un clavier USB, vous devez utiliser evtest au lieu de showkey pour obtenir les scancodes appropriés:

J'ai pu vérifier que mes clés fonctionnaient en en les remappant en lettres :

$ cat /etc/udev/hwdb.d/90-custom-keyboard.hwdb 
evdev:input:b0003v1130p7979*
 KEYBOARD_KEY_c00cd=a
 KEYBOARD_KEY_c00b6=b
 KEYBOARD_KEY_c00b5=c
$ Sudo udevadm --debug hwdb --update
$ Sudo udevadm trigger

Maintenant, je peux taper des lettres avec mes touches précédente, suivante et lecture/pause. Ensuite, j'ai utilisé xdotool pour tester les clés:

$ xdotool key XF86AudioLowerVolume
$ xdotool key XF86AudioRaiseVolume

les deux fonctionnent, mais aucun des suivants ne fait rien

$ xdotool key XF86AudioPlay
$ xdotool key XF86AudioNext
$ xdotool key XF86AudioPrev

Cela me fait penser qu'Unity laisse tomber la balle avec son intégration de lecteur multimédia, d'une manière ou d'une autre. Je ne sais pas comment vérifier que Unity fait ce qu'il faut dans les coulisses. Des idées?

Les touches multimédias fonctionnent (avec rhythmbox). Ils ne fonctionnent pas avec banshee ou VLC car il y a un bogue avec banshee 2.6.2 et VLC 2.2.2 dans Ubuntu 16.04.

Une solution pour VLC consiste à définir un raccourci clavier global .

Comme @Jeffrey l'indique dans sa réponse , les touches multimédias fonctionnent avec rythmbox v.3.3. Ils fonctionnent également dans totem v.3.18.1 sans aucun ajustement nécessaire.

Aussi connu pour fonctionner avec le clavier multimédia sans fil 2,4 GHz Rosewill RKM-1600RF (RF6560)
