Como você configura o driver para uma placa de captura de TV baseada na Philips?

2

Eu tenho uma placa de TV que não consegui instalar com o Ubuntu 10.10 i386. Eu tentei vários tópicos em vários fóruns e não consegui instalá-lo.

Espero que você possa me ajudar a instalá-lo, obrigado.

Eu segui os passos até aqui e ainda nada que eu acho é 42 minha placa de vídeo é esta: link

E quando eu começo o tvtime, ele fecha automaticamente.

Você precisa ler o dmesg, ele está dizendo que você tem que especificar o cartão quando o módulo é adicionado (embora o desenvolvedor tenha decidido falar um pouco sobre isso também) você precisa saber qual placa de TV você tem e então combiná-lo para um número nessa lista no seu dmesg. Depois de ter o número, faça isso:

echo saa7134 card=100 | sudo tee -a /etc/modules

Sabemos que não é '0' porque zero foi autodetectado e não foi carregado. Mas você não especificou que tipo de cartão você tem, então você terá que descobrir qual deles é. Uma vez que você tenha feito o comando acima com o número correto, reinicie seu computador e informe aqui um registro dmesg atualizado.

Com base nas informações da resposta de Martin, você pode testar manualmente um modelo específico (a partir dos IDs do módulo com suporte do driver).:

sudo modprobe -vr saa7134_dvb
sudo modprobe -vr saa7134_alsa
sudo modprobe -vr saa7134
sudo modprobe -v saa7134 card=21

Teste, se falhar, você precisará repetir toda a sequência de comandos, mas substituindo card = 21 por um ID diferente.

Depois de encontrar o melhor id, anexe-o a / etc / modules pela outra resposta para ter certeza de que ele será configurado corretamente durante a inicialização.
