using libreelec on a rpi 2

libcec version string: CEC client registered: libCEC version = 4.0.1, client version = 4.0.1, firmware version = 1, logical address(es) = Playback 1 (4) , physical address: 1.0.0.0, git revision: 8.2.1+19-0ddf2aa~dirty, compiled on Sat Dec 16 04:54:28 UTC 2017 by chewitt@buildbox on Linux 4.4.0-81-generic (x86_64), features: P8_USB, DRM, P8_detect, RPi

tv is a panasonic TH-55DX600U sound bar is panasonic SB-HWA488

not even sure if it's sanely fixable but the tv stops sending anything but fwd/back/play etc once it recognises the sound bar is there and inputs have been switched once, i'd provide logs but there's not much going on except the buttons that come through come through and those that don't don't

willing to provide any logs or i'll just remap the media buttons to something useful, all good

you may have to read the readme https://github.com/Pulse-Eight/libcec#panasonic

only the play pause etc work, the rest of the remote is not sent through, looking at it i could try using some other codes and see what happens, thanks

Were you able to find a solution? I have the same problem, and I agree that it is the opposite of the issue explained in the readme, i.e. only the play/pause/stop/rew/ffwd buttons grouped at the bottom of the remote are passed through to Kodi, no other button is.

I power everything off, turn the TV on, followed by the soundbar, then the Raspberry Pi. All buttons work for a while, then the non-"cassette" buttons aren't passed through any more. Kodi debug logs show only the cassette buttons are detected and other buttons don't reach Kodi.

The TV is a Panasonic TX40-DX600E (2016) updated to the latest firmware (3280) - https://av.jpn.support.panasonic.com/support/global/cs/tv/download/fw/eu_2016/down_eu_uk_cis_02.html - and a Panasonic SC-HTB200 soundbar which doesn't appear to have any update available for it.

as far as i can tell the TV no longer sends the button events through to the pi once it realises the sound bar is plugged in, possibly because it thinks the bar is a player type device and might handle the remote buttons itself (just guessing). i bought a flirc usb and use another remote, sorry no good solution but if you find one please tell me lol

twelvedogs commented 2 years ago

actually there is one other way around it, connect the sound bar via optical instead of ARC but then it loses CEC

coder9 commented 2 years ago

Thank you for replying. I'm using the first workaround you suggested, but working CEC would be much better. Could I ask you to re-open this issue so maybe the developers could take a look at it?

I've attached a Kodi debug log, with debug mode enabled and component-specific logging set to the CEC library and the place where it lost button input commented.
