The Realtek rtl2832 is a chip that always come with DVB-T internally, and supports only pure DVB-T. No DVB-T2 support. As the frontend is integrated with the demux on those devices, the Kernel recognizes it as frontend0. Devices based on such chipset that supports other standards come with an extra chip for the frontend. In this case, Panasonic MN88473, with can do both DVB-T and DVB-T2. As you're adding the same frequency table for both DVB-T and DVB-T2, I suspect that Kaffeine is using the first adapter (with supports only DVB-T) when seeking for channels. As far as I remember, I didn't add any special logic there that would make it so select the better adapter when scanning the file. So, it should just get the first available one. You can easily test it by changing the adapter two for "no source" (or something different than "Automatischer Suchlauf"). With such change, when you ask to scan "Automatischer Suchlauf", it should use the second frontend (the Panasonic one). If this works, I'll take a look at the code and seek for a solution to do it automatically, but you'll likely need to test such patch, as I guess I don't have any RTL-based device with an extra DVB-T2 frontend. -- You are receiving this mail because: You are watching all bug changes.
