Eu tenho tentado configurar uma interface de áudio Edirol FA-66 no Ubuntu 12.04 LTS, para que eu possa gravar o som vindo de dois microfones conectados a ele. A interface está conectada ao meu computador usando um cabo FireWire. Agradecemos antecipadamente pelo seu interesse e ajuda!
Segui este tutorial de áudio digital FireWire (ignorei as Definir prioridades de IRQ seção, eu não estou interessado em tempo real), depois de instalar o Ffado, JACK e QjackCtl, mas eu recebo um erro que não posso resolver.
Quando eu inicio o QjackCtl (com privilégios de root), aplico as configurações descritas na seção Start Jack do tutorial acima e clique no botão Start, eu recebo um janela do erro e outra depois de fechar a primeira .
Além disso, há esses erros na janela Mensagens do QjackCtl.
18:43:18.581 ALSA connection change.

Primeiro, sei que a placa FireWire está funcionando corretamente, porque posso obter vídeo de duas câmeras FireWire conectadas à mesma placa.
Segundo, eu sei que a interface de áudio Edirol está sendo reconhecida, porque quando eu executo o comando sudo ffado-test ListDevices , ele produz a seguinte saída:
=== 1394 PORT 0 ===
Node id GUID VendorId ModelId Vendor - Model
0 0x000a47010f069020 0x00000A47 0x00000000 -

2 0x001106000000d9ff 0x00001106 0x00000000 Linux Firewire -
3 0x0040ab0000c33a09 0x000040AB 0x00010049 EDIROL - EDIROL FA-66
Terceiro, eu modifiquei o /etc/pulse/client.conf para conter a linha autospawn = no , matei o processo Pulseaudio, verifiquei que ele não estava mais rodando e reiniciei o QjackCtl. Eu ainda tenho as mesmas janelas de erro e mensagens.
Em quarto lugar, esta é a saída sudo ffado-diag . Eu não tenho certeza do que algumas dessas coisas significam, mas parece-me que toda biblioteca necessária está instalada e foi encontrada.

FireWire kernel drivers:
The new FireWire kernel stack is loaded.
This is still kind of experimental. If you encounter problems, please also check
with the old stack.
Se você ainda estiver lendo este mural, obrigado novamente! Não hesite em pedir informações que eu possa ter esquecido, vou fornecê-lo o mais rápido possível. Obrigado pela sua ajuda!
Edit: Eu acho que há algo errado com os drivers ffado, já que recebo as seguintes mensagens de erro quando executo sudo ffado-dbus-server :
