Eu uso uma placa-mãe ASUS M4A78 / EM / 1394 com um processador AMD quad core. A placa-mãe tem placa de som 5.1 on-board. Eu também tenho uma placa de som Sound Blaster Audigy PCI. O sistema tem o Windows 7 e o Ubuntu Linux 10.4 instalados em duas partições separadas.
O Sound Blaster está conectado a alto-falantes 5.1, enquanto o dispositivo de som interno está vinculado ao conector de áudio do painel frontal ao qual eu conecto meus fones de ouvido.
Quando inicializo o Windows 7, o Painel de Controle me dá a liberdade de fazer qualquer um dos dois dispositivos de áudio padrão, dependendo de eu precisar usar os fones de ouvido ou o sistema de alto-falantes 5.1. A qualidade do som através dos alto-falantes pode não corresponder à qualidade do SB 5.1, mas é aceitável.
O hardware e o software instalados para ambos os dispositivos (no Windows) estão bem.
O problema surge apenas quando eu inicializo o Linux que foi instalado recentemente. Aqui o cartão SB é funcional, mas não consigo obter qualquer saída de som através da placa de som onboard.
Eu trabalhei muito no Windows e no Unix, mas sou novo no Linux e gostaria de receber ajuda para que a placa de som onboard funcionasse. Eu tenho passado por algumas informações / dicas disponíveis na net. Estes exigiram que eu executasse alguns comandos interativamente; a saída desses testes de diagnóstico é anexada (se for de alguma ajuda). Se mais alguma informação for necessária, eu ficaria feliz em fornecer.
O comando está em negrito e o que segue é a saída.
