Hi! I have been trying to get it to work, but the output is always 0. Logs are below. Any ideas? Thank you for your work.

it appears your DVB-C card has problems to report correct results to 'dvbsnoop'. Did the DVB-C card fell asleep? Maybe that:

echo 0 > /sys/module/dvb_core/parameters/dvb_powerdown_on_sleep

helps. The path may vary depending on the hardware.

Another user had a simlilar problem (sorry the posting is in German): https://www.kdgforum.de/viewtopic.php?p=235250&sid=7fd8b6cc87fc9222ad3d67de833a5862#p235250

the solution there was to use a Sundtek DVB-C card.

JamesT42 commented 5 years ago

Yes! thanks, now I can see numbers there.

I used

echo 0 | sudo tee -a /sys/module/dvb_core/parameters/dvb_powerdown_on_sleep

(sudo stuff...)
