Hello,
I have a Technisat DVB-S2 card in addition to an Nvidia Geforce GTX 1060 3GB in my computer. As operating system I currently use a triple of Win10, Mint 20.1 and Manjaro XFCE 20.2. Well, under Windows and Mint the DVB card also works fine. With Manjaro, however, since version 20.0.3 no longer. Normally, after reinstalling Manjaro, I would first update the system via Pacman and then install Kaffeine via the package manager, so that it would do a channel scan in the background while I continued to install other programs in the meantime. Well, up to version 20.0.2 this also worked, after the search run the found stations could be played back immediately. Not since 20.0.3. Because now the channels are found, but except for the EPG of the currently running channel Kaffeine shows nothing more, no picture, no sound. What has been changed in the meantime and how can I get Kaffeine to show stations again ? Other tools like the VLC player work fine on the first try, so the problem should be somewhere at Kaffeine.
As a test, I have tried other Arch-based distributions. Garuda, Archman, Arcolinux etc...same spook everywhere....Kaffeine finds stations but no longer displays anything. For other distributions that are not based on Arch (e.g. Mint, Ubuntu etc.), everything works fine. So what happened there?

How did you upgrade from 20.0.2 to 20.0.3?
And Kaffeine was installed the whole time?

It was a complete reinstall, not just an upgrade.

OK.
Sounds very weird to me to make a complete reinstall for a minor version; I'm pretty sure would have been sufficient.

Be that as it may, maybe something changed... well, that didn't sound very clever.

please.

And try to open it from a terminal and see if you get meaningful error messages when you try playback.
