O volume às vezes vai para o máximo

Question

Se eu aumentar o volume no Ubuntu 17.10, às vezes ele continua no máximo. Dado que eu só apertei o botão uma vez, deveria teoricamente incrementar o volume apenas em um passo. Note que estou ciente do problema que está acontecendo com os botões de controle de volume, e não de qualquer outro método de ajustar o volume, já que nunca os utilizo.

Como posso consertar isso?

Answer 1

Eu fiz algumas pesquisas e seu problema pode ser que seus botões de volume alterem o volume em mais do que deveriam, talvez em 100% em vez de 5%. Tente alterar suas configurações conforme ilustrado neste gif:

Ogifédestepostaqui:

Como faço para definir um teclado personalizado atalho para controlar o volume?

que fala sobre a mudança do comando executado quando você pressiona os botões de volume.

Se isso não funcionar, você pode seguir a rota bruta e adicionar um lançador de comandos à sua barra de ferramentas com alguns ícones. Eu fiz esse gif para mostrar o que quero dizer:

comandos:

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

Estou executando o Ubuntu MATE no gif que tem algumas pequenas diferenças em relação ao Ubuntu normal, mas eles ainda devem funcionar da mesma maneira, espero que isso tenha ajudado!
