I have installed two separate PCI tv tuner cards in my HP Proliant N40L microserver running Ubuntu 12.04.2 LTS. Both cards are successfully recognized and registered as DVB-T cards

Attempting to use DVB utilities (scan, w_scan) or other software (TVHeadend) returns no signal. There are no errors messages in dmesg (see below). One of the cards has successfully been used in a Windows PC plugged into the same antenna cable, so I feel confident that the hardware and signal are fine.

What are the next steps to troubleshoot this issue?

I have a Terratec Cinergy TStick+ (ID 0ccd:00d7).

None of brand/device drivers seem to work, and I instead had to use media build:

LinuxTV > use latest experimental drivers/patches

( link provides steps to install 'Media Build' driver. )

What shows up in lsusb, with this device onboard?

Can you provide output for:

lsusb

lsmod | grep dvb

dmesg | grep dvb

  • Correct. But the comments field does not support sufficient layout to provide the detail I needed. I am attempting to answer, but still need further information.
