13.04 Logitech emparelhamento adaptador de alto-falante bluetooth, mas sem saída do mixer

Question

Eu tive que mudar

[General]
Enable = Socket

em /etc/bluetooth/audio.conf para conseguir parear. Mas agora que estão, eu não recebo uma saída no pavucontrol.

O que posso fazer para que funcione?

Atenciosamente,

EDIT2:

No pavucontrol eu tenho "(34) Logitech Adapter". Se eu mudar o perfil de "Off" para "HighFidelity Playback (A2DP)", recebo esta mensagem do pulseaudio:

W: [pulseaudio] module-bluetooth-device.c: Profile has no transport

EDIT3:

Engraçado. Desconectando o dispositivo via blueman falha pulseaudio:

E: [pulseaudio] hook-list.c: Assertion 'hook->n_firing == 0' failed at pulsecore/hook-list.c:51, function pa_hook_done(). Aborting.

EDIT4:

O upgrade para o 13.10 também não resolveu o problema. Parece haver alguma incompatibilidade com bluez e pulseaudio e certo hardware ...

Muito tempo eu estava procurando solução e finalmente me ajudou nesse link: link

Ubuntu 14.04 Audio sink problem to Logitech Wireless Adapter

Hello, jcmoriaud. I had this problem recently as I bought a bluetooth speaker and attempted to connect to it with my laptop. It kept giving me "Connection Failed: Stream setup failed". I eventually figured out how to make it work like this. You need to have pulseaudio installed, which you can check for in Synaptic Package Manager by typing pulseaudio into the search bar. You can install it from there if it isn't already installed. Next, you need to install pavucontrol, either in Synaptic Package Manager, or by running this in the terminal. Code: sudo apt-get install pavucontrol This is the unfortunate part. Every time you boot, you need to run this command in the terminal before any bluetooth devices attempt to connect. Code: pactl load-module module-bluetooth-discover You can now go into the bluetooth manager and tell it to connect to the device as an A2DP audio sink. Now, finally, if you go into the PulseAudio Volume Control, on the Playback tab, you can choose the option to send audio through the bluetooth device. Good luck with this."

Eu uso isso com o Blueman (GTK + Bluetooth Manager)

    

Answer 2

Depois que eu limpei o teclado, não havia mais áudio no meu sistema estéreo, conectado com um clone do dongle Bluetooth da Logitech Audio ao meu laptop Ubuntu.

Depois de muitas horas desperdiçadas de pesquisa, cheguei a esta solução simples:

1. Verifique se há uma conexão. Quando você toca a música, você pode ver a transferência do MB subir (= datatranfer).
2. em uma janela de terminal, execute pavucontrol
3. no pavucontrol, vá para a aba 'audio output' (estou usando a versão holandesa, então não tenho certeza se ela é chamada em inglês).
4. Procure seu dongle bluetooth. O meu foi chamado de 'Adaptador BT Esinkin'.
5. No meu caso, o 'Adaptador BT Esinkin' foi desativado. Depois de clicar no botão mudo, a música entrou pelos alto-falantes, carregada e limpa. Sim!

    

Answer 3

Eu tenho tido problemas semelhantes. Consegui fazê-lo funcionar removendo o Socket da linha de ativação em /etc/bluetooth/audio.conf referenciada no início da questão. Em seguida, na linha de comando, execute:

pactl load-module module-bluetooth-discover

Então você deve conseguir se conectar corretamente ao dispositivo de áudio bluetooth.
