EDIT (Mais uma vez ..)

Depois

gksu gedit /etc/modprobe.d/alsa-base.conf Change options snd-usb-audio index=-2 to 'options snd-usb-audio index=1

Then plug in your headset again.

Perdi a saída digital e meus fones de ouvido se tornaram saída:

Answer 1

Parece-me que você está usando um kernel customizado, já que o linux 3.2.7, conforme listado em sua saída uname -a tem um número de versão maior que o kernel 12.04 do release atual (3.2.0-29). (Também é menor que o atual kernel 12.10).

Olhando para a saída de lsmod , podemos ver que não há nenhum módulo snd_usb_audio na lista de módulos carregados. Você precisa disso para executar a maioria dos dispositivos de áudio USB que usam o padrão USB para dispositivos de áudio.

O comando locate lista vários módulos snd_usb_audio, mas não para o kernel em execução.

• Eu sugiro que você use um kernel padrão e veja se isso não detecta e suporta seus fones de ouvido.

• Se você tiver compilado o próprio kernel personalizado, você pode querer fazer esse trabalho, sugiro fazer um módulo snd_usb_audio alterando as variáveis de configuração do kernel correspondentes, recompilar o kernel e executar make modules_install também como make install para reinstalar o kernel personalizado refeito. Eu reconheço que este kernel pode ter snd_usb_audio ligado ao kernel, nesse caso eu não sei porque o kernel customizado não está sendo usado corretamente para instalar os dispositivos de áudio necessários.

CONFIG_SND_USB=y
CONFIG_SND_USB_AUDIO=m

    

Answer 2

Com base na saída lsusb -v , o subsistema snd_usb_audio do kernel Linux deve alocar os dispositivos de controle e pcm para o seu dispositivo e orientá-los.

Analisando este post, pode valer a pena tentar essa solução:

gksu gedit /etc/modprobe.d/alsa-base.conf

Alterar options snd-usb-audio index=-2 para 'options snd-usb-audio index=1

Em seguida, conecte seu fone de ouvido novamente.

Se isso não funcionar, por favor, execute lsmod e coloque a saída em sua pergunta.

Se snd-usb-audio não aparecer na lista, por favor, tente modprobe snd-usb-audio , e capture / var / log / syslog quando você o fizer. Naquele momento, por favor verifique também lsmod e / proc / asound / devices e / proc / asound / cards e procure a interface novamente.
