Instalei duas placas de sintonizador de TV PCI separadas no meu micro-servidor HP Proliant N40L executando o Ubuntu 12.04.2 LTS. Ambos os cartões são reconhecidos e registrados com sucesso como cartões DVB-T
A tentativa de usar utilitários DVB (scan, w_scan) ou outro software (TVHeadend) não retorna nenhum sinal. Não há mensagens de erro no dmesg (veja abaixo). Um dos cartões foi usado com sucesso em um PC com Windows conectado ao mesmo cabo de antena, por isso me sinto confiante de que o hardware e o sinal estão bem.
Quais são os próximos passos para solucionar esse problema?

Eu tenho um Terratec Cinergy TStick + (ID 0ccd: 00d7).
Nenhum dos drivers de marca / dispositivo parece funcionar e, em vez disso, precisei usar configuração de mídia :
LinuxTV > usar drivers / patches experimentais mais recentes
(o link fornece etapas para instalar o driver 'Media Build'.)
O que aparece em lsusb , com este dispositivo a bordo?
Você pode fornecer saída para:
lsusb
lsmod | grep dvb
dmesg | grep dvb
