    HDMI CEC broken/not working

    Hi,
    Anyone here also having issues with HDMI CEC?
    I've got a Samsung TV and unfortunately HDMI CEC isn't working at all... Anynet+ on the TV fails to connect. I've tried to enable debugging and observed what's happening in the log as well as sending commands and unfortunately nothing that would require successful Anynet+ connection establishment is registered by the TV. I do see commands going to and from the TV and but due to the fail in the connection establishment things like volume up /down or anything else doesn't work.

    This seems to be OpenATV or even OpenEmbedded related because I've tried a few OE based images and none of them have a working HDMI CEC support on DUO 4K SE.
    Please bear in mind that I have tried OpenPLI and there HDMI CEC is working fine.

    My previous box - VU+ Ultimo had no such problems.

    I've tried all 6.4 and even the nightlies 6.5 and none of them have a working HDMI CEC on Vu+ DUO 4K SE.

    Any suggestions?

    Hi I also have a similar problem. I did manage to get my OpenATV to eventually be recognised but only by following some instructions (which I thought where crazy but sort of worked). Basically remove all HDMI cables from Samsung TV, switch off at power and leave off for about 15-20 minutes, then switch it back on, enable / disable the HDMI CEC setting on the Samsung and then plug in your OpenATV box. The Samsung will recognise a device is connected, pick 'Manual' - do not try and get the Samsung to suggest a box. At this point the HDMI CEC was/is working for me. The only problem is the Channel+ / Channel- keys do not work, but at least the navigation with the Samsung Remote works fine. I then plugged back in all my other HDMI devices and so far it has stuck.

    Basically I think unless the Samsung TV has the exactly match for the device it will mess up the HDMI CEC connection, the only way to leave it with generic CEC support is to 'go manual' with the options.

    Hope this help. Its annoying that I could not get the Samsung to recognise any of my OpenATV devices as 'Set top box' but at least this way it allows me to use the samsung remote for navigation, channel selection etc

    Thanks for this.
    I'll try it out... It's gonna be a pain to unplug everything but I'll check it out. The only concern I have is that even with ultimo it was common for the tv to start freak out every once in a while and the only way to get it sorted was to restart the tv and my Sony amplifier.

    No luck.
    Still the same.

    here's logs from the CEC log:

    Device search by the TV:

    23:46:14.1341 <Rx:> 05 A0 00 00 00 00 00 00 <Audio System><Vendor Command With ID><0><Vendor Specific Data>


    And once the search is finished and I choose the vuduo4kse to establish the connection:
    23:46:26.6247 <Rx:> 00 8F <TV><Give Device Power Status>
    23:46:26.8757 <Tx:> 00 90 62 27 5C 78 30 30 27 <TV><Report Power Status><unknown>
    23:46:31.6266 <Rx:> 00 8F <TV><Give Device Power Status>
    23:46:31.8775 <Tx:> 00 90 62 27 5C 78 30 30 27 <TV><Report Power Status><unknown>
    23:46:36.6275 <Rx:> 00 8F <TV><Give Device Power Status>
    23:46:36.8783 <Tx:> 00 90 62 27 5C 78 30 30 27 <TV><Report Power Status><unknown>
    23:46:41.6279 <Rx:> 00 8F <TV><Give Device Power Status>
    23:46:41.8788 <Tx:> 00 90 62 27 5C 78 30 30 27 <TV><Report Power Status><unknown>
    23:46:46.6275 <Rx:> 00 8F <TV><Give Device Power Status>
    23:46:46.8783 <Tx:> 00 90 62 27 5C 78 30 30 27 <TV><Report Power Status><unknown>
    23:46:51.6281 <Rx:> 00 8F <TV><Give Device Power Status>
    23:46:51.8790 <Tx:> 00 90 62 27 5C 78 30 30 27 <TV><Report Power Status><unknown>


    So clearly whatever the box is sending back to the TV in "Report Power Status" is not being recognized.

    OK success...
    Just flashed the 6.4 nightly 20210129 and CEC started working.
    Here are the logs from a successful SCAN followed by a connection attempt and volume test:
