Questions[dvb-t](ubuntu)

When i connect my EVOLVEO SIGMA T2

and type lsusb in terminal,

linux identifies new device as ID ID 0572:c68a Conexant Systems (Rockwell), Inc.

but w_scan command returns only error

w_scan version 20170107 (compiled for DVB API 5.10)
using settings for CZECH REPUBLIC
DVB aerial
DVB-T Europe
scan type TERRESTRIAL, channellist 4
output format vlc xspf playlist
output charset 'ISO-8859-1'
Info: using DVB adapter auto detection.
main:4007: FATAL: ***** NO USEABLE TERRESTRIAL CARD FOUND. *****
Please check wether dvb driver is loaded and
verify that no dvb application (i.e. vdr) is running.

How can I install driver for EVOLVEO SIGMA T2 and then successfuly scan for dvb-t & dvb-t2 channels ?

I have followed all steps in this other question, but it's not working for me on 16.04.

This is what I got:

I have a strange problem with Kaffeine after trying Gnuradio. I am running Ubuntu 14.10 and Kaffeine was running out of the box with a RTL-2838 USB DVB-T stick.

After doing some experiments with Gnuradio I tried to watch TV with Kaffeine, but it doesn't recognize the DVB-T stick any more.

If I remember there used to be a /dev/dvb directory which is not created any more when I plug in the DvB-T stick.

dmesg |grep -i dvb
-- reports nothing -- 

If I remember correctly there used to be some DVB driver information in the dmesg output.

Also w_scan reports an error, no usable terrestrial card found.

Has anyone observed the same problem and maybe found a solution?

I have only one question, can I use a DVB-t tunner there? I have a DVB- t tunner Evolve and I would like to use it in the Ubuntu system.

• My questions are : Is it possible?
• Is there any driver for it?
• Can you plese help me with that?
• Which program I have to use to use it?

Because I have to have a dual boot system with Windows only because of this in case of your help.

This is on Ubuntu 12.04 - I installed the DVB-Realteck-RTL2832U-2.2.2-10tuner-mod_kernel package, I installed GnuRadio, I installed the rtl_fm and I just keep getting more and more confused -- I recognize that this device can monitor police radio, digital FM, weather channels, you name it, but all I really need is to run a simple command line and hear a plain ordinary FM station streaming through my speakers.

The closest so far is the command:

rtl_fm -f 96.3e6 -s 48000 - | aplay -r raw -f dat -c 1

but the sound quality is atrocious.

Any and all guesses or pointers to resources are welcome. I haven't been able to find anything through the Google searches that gets me any closer to a nice clean stereo FM signal. GnuRadio seems completely intractable although I am certain that, once one figures out what it is that it does, it makes perfect sense ;)
