Microfone não capturando som no 12.04 Lenovo G580

3

No Skype e no aplicativo Gravador de som, não estou capturando nenhum áudio do microfone embutido. Não sei porquê. Caso contrário, a saída de som está funcionando bem.

Eu tentei executar gstreamer-properties e configurar o plugin de entrada padrão para PulseAUdio também (para corresponder à saída), e isso não ajudou.

Eu tentei executar alsamixer -V all e só recebo duas entradas relacionadas a entradas: Capture(L R) , que está em 100 e não está mudo (não pode ser nenhum), e Analog Mic Boost , que está em 20db.

Informações adicionais: a câmera (vídeo) está funcionando bem no Skype e na Kamerka.

Por favor, você pode me ajudar a colocar meu microfone para funcionar?

Eu tenho um Lenovo IdeaPad R580-3087 com a mesma placa de som (Controlador de Áudio de Alta Definição Panther Point da Intel Corporation, rev 04). Eu tentei usar gstreamer-properties sem efeito. No entanto, em busca de soluções, eu li como o microfone parou de funcionar depois que o kernel foi atualizado para uma nova versão, então instalei a versão 3.5 usando este guia de atualização do kernel .

Agora eu posso gravar som usando o gravador de som gnome, teste de chamada do Skype, mas gnome-control-center sound ainda parece desativado como se não houvesse microfone. Isso pode acontecer porque, em gstreamer-properties , alterei as configurações de personalizado para PulseAudio e, em pavucontrol na guia Entrada, o microfone parece ser exibido como trabalho por cerca de 3 segundos, mas ainda posso gravar som ou usar o Skype.

Então eu não sei porque parece que não funciona, mas funciona. Então eu posso usar o Skype e outras mídias de recodificação. Se alguém tiver mais informações eu ficaria muito grato.

A adição da linha a seguir a /etc/modprobe.d/alsa-base.conf me ajudou e pode ajudar você também:

options snd-hda-intel model=auto
