Samsung UE43RU7179 not receiving button presses #570

Open janecker opened 3 years ago

janecker commented 3 years ago

Hi all,

first of all thank a lot for the software and some information about my setup:

TV: Samsung UE43RU7179UX2G Client: Raspberry Pi 4 8GB libcec version: 6.0.2, git revision: libcec-6.0.2+1-76551ea

Now to my Problem: It seems like I am unable to receive any remote control actions with the PI. I am able to see the TV via the cec-client[1], and I am also able to change the input [2]. I also receive cec updates when I switch the source using the TV remote [3]. But I dont see any output whatsever in the client if it is running as in [3] and I press any button on the remote.

I don't have the feeling that this is really a software bug or anything, but I am wondering if there are any known limitations of Samsung TVs or if there is any setting I could be missing. I am happy to provide further information or run additional tests.
