Hello everybody!
I searched the net for a while but did not find a solution for my problem. So I am hopeful, that somebody of you can help me out.
I am running LibreELEC 8.0.2 on a RPi 3.
An IR receiver is connected via GPIO. It is feeded with an XBox One Media Control.
For Live-TV I am using an PCTV 461e USB stick (DVB-S/S2).
Everything works fine until I connect the DVB-stick. From then on the responsiveness of the remote control is unreliable, since some of the button pushes are not recognized by Lirc/Kodi.
In my opinion this behaviour is reasoned in the fact that the DVB-stick has got it's own IR receiver and therefore two IR receivers are working inside the system and interfere with each other.
Part of dmesg output:

If I run ir-keytable, I got the following output:
# ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event0) with:
Driver em28xx, table rc-pinnacle-pctv-hd
Supported protocols: rc-5 nec rc-6
Enabled protocols: rc-5
Name: 1-1.3: em28178#0 IR
bus: 3, vendor/product: 2013:0258, version: 0x0001
Repeat delay = 500 ms, repeat period = 125 ms
If I run ir-keytable without the DVB-stick attached to the RPi (the case when everything works fine!), the output is as follows:
# ir-keytable
Couldn't find any node at /sys/class/rc/rc*.
For my limited knowledge of lirc it seems strange that the best working config seems not to use the lirc components.
Perhaps it is useful to know the lirc-processes that are running on my Pi:
# ps -ef | grep -i lirc
281 root 0:00 /usr/sbin/eventlircd -f --evmap=/etc/eventlircd.d --socket=/run/lirc/lircd

463 root 3:04 /usr/lib/kodi/kodi.bin --standalone -fs --lircdev /run/lirc/lircd
861 root 0:00 grep -i lirc
I think that the solution for my problem is to disable the IR receiver of the DVB-stick, but I don't know how to achieve it.
May somebody help me? Thank you very much in advance!
Nico.
