Oi Xisberto
No seu comentario vc menciomou em criar os link e adicionar o usuário no grupo
video,
mas mesmo realizando o comando:
sudo gpasswd -a afonso video
e criando os links /dev/radio, /dev/video
não consigo ver o vídeo, (refere que eu tenho que mudar a configuração do V4L2
O tuner do radio mostra a procura das estações, mas não me permite mudar a
fonte de mixagem (fica travado no dig1).
Atualmente meu sistema se encontra assim:

Conforme já tinha dito, o sistema reconhece a placa através do
/etc/modprobe.d/bttv, optios e rc.local, não cria os link /dev/radio
e/dev/video e não insere o usuario no grupo video, não permite acesso ao video
e radio da placa.
Onde será que esta o erro de configuração?
desde já agradeço as respostas e espero estar sendo util para melhorar o
sistema.
