Tuning failure with PCTV 292e and Raspberry Pi 2

Postby ikyrre » Fri Feb 27, 2015 8:45 pm

I had a problem with "Tuning failure" on all Swedish channels on my Raspberry pi 2 with PCTV 292e and DVB server/source 5.1.0 11069 on newly installed and updated Raspbian.
I tried uninstalling and reinstalling the software without any resolution.
The antenna is ok, and the tuner works fine with the TVCenter on Windows, where I receive all channels including the DVB-T2 HD-channels.
The DVBserver and source works fine out of the box with my old tuner PCTV 72e, finding all DVB-T channels.

I searched the DVB log files and found:
Direct firmware load for dvb-demod-si2168-b40-01.fw failed with error -2
[ 622.287195] si2168 1-0064: Direct firmware load for dvb-demod-si2168-02.fw failed with error -2

I downloaded these two files from the internet and put them in my /lib/firmware.
Now the DVB source/server works perfectly with my PCTV 292e on the account of all DVB-T channels, but I do not get any DVB-T2 channels listed (like SVT1 HD and SVT2 HD).

My questions are:
1. Why did the PCTV 292e not work at all out the box, while the older PCTV 72e does? You have the 292e as a reference tuner.
2. Why did I have to download extra firmware files after searching all of internet to be able to tune in DVB-T-channels?
3. Why does the DVB-T2 tuning not work?
4. What can I do to fix this problem?

I am sorry, but drivers for tuners at all Linux systems use V4L drivers which have a problem (except NASes, they use drivers from dvblink who knows how to switch dvb-t and dvb-t2)
Look at the same problem here viewtopic.php?f=106&t=28794
