Sem saída de áudio padrão via Jack - Zoom H5 como interface de áudio USB - Ubuntu 14.04
0
Antes de começar, uso o kernel 4.11.2 de baixa latência, a prioridade em tempo real é ativada em /etc/security/limits.conf . O grupo de usuários em tempo real etc. foi configurado. Jack parece funcionar bem com a ALSA.
Eu uso o gravador de áudio 'Zoom H5' como uma interface de áudio USB com o Ubuntu 14.04. O Zoom H5 possui 2 modos diferentes de interface de áudio: (1) ‘Stereo’ - que permite gravar um canal estéreo e (2) ‘Multitrack’, que permite gravar 4 canais mono de uma só vez.
EDIÇÃO UM
Se eu selecionar "Estéreo", o Zoom H5 é reconhecido como uma versão predecessora (o Zoom H4) como uma opção de entrada e como uma opção de saída pelo ALSA.

Minhas perguntas são:
Problema um: Qualquer chance de obter o sinal de áudio roteado para um software / os alto-falantes Intel (hw: 1)?
Problema dois: Como recuperar a saída da Intel enquanto mantém a entrada do Zoom H5 como Multitrack?
