Bluetooth: O emparelhamento de duas máquinas do Ubuntu 13.10 para a transmissão de áudio falha

Question

Estou tentando transmitir áudio por bluetooth do meu laptop para o meu nas. Ambos executam o Ubuntu 13.10.

Até agora, transmionei com sucesso músicas de três diferentes telefones Android para o nas.

O par nas com dispositivos Android sem qualquer configuração, eu mudei a classe de dispositivo para 0x200414 (obtido de link ) que é uma classe de dispositivo de áudio.

Ao tentar emparelhar as duas máquinas Ubuntu usando o GUI, recebo a mensagem:

'Configuração de "nas" ist gescheitert' ('Configuração de' nas 'falhou').

Abaixo está o arquivo de log do nas ( 00:1E:10:00:14:F6 ):

Emparelhar os dispositivos usando bluetooth-agent e um pino fixo funciona, no entanto, parece haver um problema com pulseaudio agora:

Answer 1

Eu tive um problema semelhante devido à falta de um agente em execução. Isso foi corrigido Ubuntu 14.04 Bluetooth Magic Mouse não emparelha (nenhum agente disponível)
