Eu tenho um alto-falantes bluetooth Wren V5US que estava funcionando bem com o meu Ubuntu 16.04 LTS. Eu reiniciei meu sistema ontem e ele não se conecta mais automaticamente. Eu sinto que eu poderia ter feito algumas mudanças (principalmente com o pulseaudio) quando eu inicialmente configurá-lo para fazê-lo funcionar, mas eu não me lembro mais (e poderia ter sido antes de atualizar para 16.04).
Quando uso o gerenciador bluetooth, ele mostra o alto-falante por um ou dois segundos antes de desaparecer. Isso continua se repetindo. Eu tenho o bluetoothctl em execução e ele continua registrando essas linhas:
[NEW] Device 00:17:53:73:95:DC V5US14_7395DC
[CHG] Device 00:17:53:73:95:DC Connected: no
[DEL] Device 00:17:53:73:95:DC V5US14_7395DC
Eu também tenho o blueman-assistant em execução e ele registra as seguintes mensagens:

Existem muitos tópicos com problemas semelhantes, mas não sei qual deles se aplica a mim. Eu não queria sair por aí tentando todos eles e bagunçando minhas configurações.
