Hi Audioniek,
impressive research. I can add that the DNOQ44QCH106A indeed works with E2, including your image; however, only DVB-T channels are found while channels in the DVB-T2 standard cannot be found. With the stock firmware, both types are found. I also made some tests. With your E2 firmware (the same holds for HDMU from 2017), I tried the following
That is, the tuner is recognized as DVB-T only, not DVB-T2, so it seems plausible that the channel search does not even attempt to tune in to channels in DVB-T2 format. On the positive side, it seems that the tda28278 driver (mind the 7) is compatible with the tda18218 to some extent, when it comes to DVB-T type channels.Code:cat /proc/bus/nim_sockets NIM Socket 0: Type: DVB-S2 Name: Availink AVL2108 DVB-S2 Frontend_Device: 0 NIM Socket 1: Type: DVB-T Name: Samsung CXD2820 DVB-T/T2 Frontend_Device: 1
I hacked the file driver/player2/linux/drivers/media/dvb/stm/dvb/e2_proc/e2_proc_info.c to force the type of the tuner to DVB-T2 (confirmed by nim_sockets). As a result, the Enigma2 menu mentioned DVB-T/T2 in the headline of the channel search while it previously only showed DVB-T there. Unfortunately, this time no channels were found at all - neither DVB-T nor DVB-T2 ones. Maybe the tuner crashed this time due to the wrong driver being used.
One thing I find curious: the build system includes the file driver/frontends/pace7241/tda18218.c (and related headers). However, I am not sure to what extent these files are useful.
