DVB-T2 ZDF Mux in Leipzig/Germany at 482MHz not working

Tobias Weiß · 2021-04-10T18:44:43+00:00

Hello, I use DVB-T2 with tvheadend server on my Raspberry Pi3 B (Kodi 18 - libreelec 9.2.6). I got all public channels working but ZDF, 3Sat and arte. These...

Tobias Weiß

Can this OpenElec post help? It suggests a 02 firmware file: dvb-demod-si2168-b40-02.fw

https://tvheadend.org/d/5319-solved-workaround-hauppauge-solohd-not-working-new-product-id

RE: [SOLVED/WORKAROUND] Hauppauge SoloHD not working/new product ID - Von Giacinto Lo Meo vor mehr als 3 Jahren hinzugefügt I solved my problem and now i have the Hauppauge WinTV Solo HD id 2040:8268 fully functional with Ubuntu 16.04.3. The steps that i have done are the following. I don't know if all of them are necessary, however i hope this can help someone with this problem. I've installed V4L-DVB as explained here: TVHEADENDMIGRATIONSTART65ce02538a8d4e349b048fcac922ff37TVHEADENDMIGRATIONEND I've downloaded dvb-demod-si2168-02.fw (TVHEADENDMIGRATIONSTART6ec164a1ea8b48369e7126d1123e08bdTVHEADENDMIGRATIONEND and copied to /lib/firmware I've installed the package linux-firmware-nonfree -> downloaded from TVHEADENDMIGRATIONSTART3075da93dd82445d8bf4aa3865336778TVHEADENDMIGRATIONEND selected my architecture and then sudo dpkg -i linux-firmware-nonfreexx.deb_
Then the magic commands suggested by Sir Cypher:

I have created a file dvbstick.sh

#!/bin/bash
modprobe em28xx card=94

echo "2040 8268" > /sys/bus/usb/drivers/em28xx/new_id

maked it executable with sudo chmod +x dvbstick.sh

and then, because the udev rule not work for me, i have added the script to /etc/rc.local_

You need to figure out how to write to the filesystem. I don't know what kind of filesystem it is and how it's used, so it's probably a good idea to ask the maintainers of LibreELEC.

Tobias Weiß

Maybe I could mount the sd card on my laptop. What changes do you suggest?

Flole

I suggest updating the Firmware if it's outdated.

Tobias Weiß

should I take the 01.fw file which worked on my laptop or should I take the 02.fw file suggested for OpenElec?

Flole

Use the one that worked, the other one is probably already in there.

Tobias Weiß

When I mounted the SD card on my laptop, I couldn't find any firmware file. The orders must be created when the raspberry is booted. I will ask on Kodinerds forum how to change the file.

Tobias Weiß

Two days later I can say, that it is not up to the firmware file:

I "IIRC" the firmware, when creating /storage/.config/firmware and put it inside - from thjs post:

https://forum.libreelec.tv/thread/24083-exchange-outdated-dvb-t2-firmware-with-read-only-filesystem/

But the error remains. There are some channels found in 482MHz, but without name. The channel names will be included later. And all the other channels not delivered in 482MHz work correctly.

Tobias Weiß

Can it be the kernel version? on my laptop I have OpenSuse Tubmbleweed with Kernel 5.11.11-1-default, on my Raspberry there is a Kernel 4.19.127.

Tobias Weiß

In the libreelec forum it was suggested to do the command dmesg. The last 50 lines are repeating this:

em28xx 1-1.4.1:1.0: write to i2c device at 0xc8 failed with unknown error (status=128)

em28xx ist the kernel modul which is needed for the dvb-t2 stick.

I load the whole output file dmesg_out.txt

Tobias

Tobias Weiß

Is there an conflict between two firmware files?

[ 7.125042] em28xx: Registered (Em28xx Input Extension) extension [ 7.391689] si2168 8-0064: firmware version: B 4.0.11 [ 7.397775] si2157 9-0060: found a 'Silicon Labs Si2157-A30' [ 7.447904] si2157 9-0060: firmware version: 3.0.5

Tobias Weiß

Is it important that I use a USB hub with its own power supply?

Tobias Weiß

I did put away the USB hub and connect the DVB-T2 adabter directly to the raspberry. Now none of the channels are correct. Before only the ZDF Mux didn't work correctly.

I attach the dmesg output for the direct connection

Tobias Weiß

It's not the USB hub. I made a new SD card and connected the DVB-t2 adapter directly to th raspberry from the first boot on. The problem is the same: no ZDF mux, the other muxes work.

Tobias Weiß

By the way, the downloaded firmware is older than the delivered one:

from Haupage page: 4.0.11
from libreelec: 4.0.25

Tobias Weiß

I think now the DVB-T2 stick is defect. After all it doesn't funk on my laptop, which did at the very beginning!

Eg Tv

Hmm, I think I have exactly the same problem (also ZDF missing in Leipzig with WinTV soloHD from Hauppauge):

Manually tuning to 482000 kHz with VLC gives nothing.

Ok, manually setting this in VLC is working

This works for me (located in Leipzig).

I think they messed up something on our broadcaster Leipzig/Messegrund.

There’s something about the ZDF mux that seems to upset some tuners.

I have tried a PCTV 290e (similar to the WinTV Solo HD which I think is equivalent to PCTV 292e) and it will not lock the ZDF HD mux in Cologne. I can see the Colonius tower transmission antenna less than 2km away, but there is no signal for ZDF on channel 29. The two ARD/WDR muxes are received with no problem at all, the signal is very strong.

The same applies with an Xbox TV tuner in Linux using TVHeadend. ARD/WDR works but ZDF does not work.

I noticed the same last year using the PCTV 290e when visiting the border area between France and Germany (Strasbourg/Kehl). I could receive the two ARD/SWR multiplexes from the Baden Baden/Fremersberg transmitter, but there was no signal for ZDF. I thought at the time that it was because the signal was just not strong enough, but I now think it was also because the device has problems with decoding the configuration used by ZDF.

Tobias Weiß

Hallo,

It is a bit mortifying (peinlich), but I solved my problem by moving the

antenna. Maybe the ZDF-3Sat Mux is a bit vulnerable.

And when I tried some sticks I remember there was one stick which stopped linux support at one several serial number. But I don't remember if it was a satellite or trestric stick.

kind regards
Tobias
