No tuners found on newer versions of Tvheadend

Dazz

Hello,

I'm running Fedora 43 with a Digital Devices M2- tuner card. The default version of Tvheadend that Fedora provides, works OK with this tuner, but the version is quite old (4.3^{20241008git26ec161}-11.fc43). Wanted to upgrade to a new version for some vaapi-related fixes.

Downloaded the latest rpm-version for Fedora 42 (4.3-2500_g7de8bf482.fc42).
It installs fine and the tvheadend.service also starts and I'm able to login to the WebUI, but in the Configuration -> DVB Inputs. the TV adapters list is now empty. Rolling back to the older version restores it to a functional state.

Does anyone know, what might cause it or how to start debugging it?

I've been trying to run "sudo systemctl restart tvheadend.service" on a terminal, while running "sudo journalctl --follow" on another terminal and I don't see anything out of the ordinary.

Output says this:

Please check if your older Version (4.320241008git26ec161-11.fc43) have the configuration Directory located at the same Spot as the new Version (4.3-2500g7de8bf482.fc42).

The Configuration Directory for the New Version (4.3-2500g7de8bf482.fc42) should be /var/lib/tvheadend/ like your Log is saying -> "running as PID:94067 UID:972 GID:972, CWD:/ CNF:/var/lib/tvheadend/config"

The Old Version (4.320241008git26ec161-11.fc43) could might have the old path /home/hts/.hts/tvheadend/ as default Configuration Directory.

If it is like that, you can copy the files over from the old Destination to the new one and everything should be like before with the old Version.

Thank you for the reply.

Both versions seem to have the same configuration directory. I have no ".hts" directory in the home folder at all. And it seems that tvheadend is making backups of the previous configurations in the /var/lib/tvheadend/config/backup

It occurred to me that there is a different group for the old version (tvheadend), while all the newer versions seem to have a "video" group. I wonder if it is related to some permissions.

edit: That's it! The user tvheadend was not part of the "video" group. Changed that and now it works!

Also check dmesg for any messages regarding missing firmware for your adapters.
