Le volume va parfois au maximum

Si je monte le volume sur Ubuntu 17.10, il continue parfois au maximum. Étant donné que je n’ai appuyé que sur le bouton une fois, il ne devrait théoriquement incrémenter le volume que d’un pas. Notez que je ne suis au courant que du problème rencontré avec les boutons de contrôle du volume, et de toute autre méthode de réglage du volume puisque je ne les utilise jamais.

Comment puis-je résoudre ce problème?

J'ai fait des recherches et votre problème pourrait être que vos boutons de volume modifient le volume de manière excessive, peut-être de 100% au lieu de 5%. Essayez de modifier vos paramètres comme illustré dans ce gif:

change command run from volume key press

Le gif est de ce post ici:

Comment définir un raccourci clavier personnalisé pour contrôler le volume?

qui parle de changer la commande exécutée lorsque vous appuyez sur les boutons de volume.

Si cela ne fonctionne pas, vous pouvez suivre la route brute et ajouter un lanceur de commandes à votre barre d'outils avec des icônes. J'ai créé ce gif pour vous montrer ce que je veux dire:

adding a volume button to your toolbar

commandes:

amixer -D Pulse sset Master 5%+
amixer -D Pulse sset Master 5%-

Je suis sous Ubuntu MATE dans le gif qui présente quelques légères différences par rapport à Ubuntu normal, mais ils devraient tout de même fonctionner de la même manière, espérons que cela vous aidera!
