[Resolved]Mythtv-setup takes only the DVB-T2 input of my Digital Devices Cine C2T2 V7

[Woodpacker]

Hello, I have the problem that Mythtv (0. 30) only takes the DVB-T2 input of my Digital Devices Cine C2T2 in the mythtv-setup. For info, I upgraded from 0. 28 to 0. 29 under ubuntu 16. 04LTS. Everything was still good then and I did the long delayed update from 16. 04LTS to 18. 04LTS. Then the problems started, first my FB (imon) didn't work properly anymore and I had a lot of fun with ir-keytable and then I stayed with Lirc (Lirc 0. 9 on hold). So FBI's back on. But the Digital Devices remains in mythtv-setup stubbornly on DVB-T2. Then I even updated to mythtv 0. 30, but without success.

I tried the following without success:
manually set input to DVB-C with dvb-fe-tool (mythtv-setup wasn't interested)
w_scan scans the DVB-C channels but with "-fc -c DE"; (Card OK)
checks conf files and mysql user

Here again:
sudo dmesg|grep -i dvb

Code: Select all

I'd really appreciate it if someone could help me out. I'm at the point where I have to do a new installation, I would prefer a less radical and less laborious solution.



Many thanks in advance

Upgrade to mythtv 31, mythtv 30 has a problem with dvb-c (for background see viewtopic.php?f=36&t=3338&p=16190&hilit ... vbc#p16190)

As you are on Ubuntu 18.04, the upgrade is in a terminal session:

Code: Select all

sudo apt-add-repository ppa:mythbuntu/31
sudo apt update
sudo apt upgrade
