  • Hello,

    I just received my Z12 Ultra as a replacement for a Z8 Pro, and I'm forced to use Kodi to play VOD content in formats higher than 5.1. :thinking_face:

    All formats higher than 5.1, whatever they may be, are only recognized as PCM. The problem lies with MTVOnline3, which is unable to decode these different formats, while Kodi handles them without any issues. :unamused_face:

  • Hello from Belgium :winking_face:

    Unfortunately, HD audio formats are no longer recognized in passthrough on MOL by the Formuler boxes, at least since the Z10, I believe.

    In any case, this is also no longer the case with the Z11 Pro (or Pro Max).

    Given the price paid for the Z12, one might have hoped they would have fixed this issue, but that is not the case.

    I discuss my tests in detail here:

    If these audio formats are truly important to you, you'll need to look towards other boxes, which we cannot mention on the forum for fear of censorship. However, there aren't many available given the current issues with Android/Google TV 14 on the models that allow it.

    Perhaps new boxes from various brands will be released in 2026, capable of doing everything correctly...

    Or, one could opt for an old box with an older version of Android TV (11), but there’s only one available, and it costs as much as the Formuler Z12.

  • Will check it tomorrow.

    But i know a channel skysports main there i see sometimes Dolby atmos. But that's a channel and not a vod.

    But i will check it tomorrow with a vod movie.

    I got 5 providers, also with dolby atmos video's categories.

    Let you know tomorrow with picture if it works. Otherwise with kodi.

    Disney+ worked from first time already with dolby vision and Dolby atmos.

    Goodday

  • Be aware that here we are not talking about Dolby Digital Plus Atmos, which is available on certain TV channels or official streaming platforms.

    It is the uncompressed format Dolby TrueHD Atmos (as well as DTS-HD) that is not supported by the Mytvonline3 application.

    But there’s no problem with Kodi since it bypasses certain security measures of the firmware.

    I didn't tested it yet.

    I know Kodi plays it.

    I setup tomorrow kodi as external player and search for movie with atmos thruehd. Then i change player to build in exoplayer and test again.


    Btw: exoplayer is in the apps section. Maby i can update it and maby it works then.

    Will let you know my findings.


    P.s. vlc player plays it, but when i play from my nas it speed forward 1 hour further in movie, the sounds begins to scratch loud and colors are changing and 10 seconds later back to homescreen and colors are normal again. Same with nova player and mx player pro. But mx player pro passthrough function still not works for years, but hangs also sometimes when i speed a movie forward.

    Maby due dolby vision image. And mx player passthrough don't work for years. Source: reddit

    Only kodi works normal on Z12 yet.

  • Good evening,

    Thank you for your input. Regarding ExoPlayer, decoding doesn't work for its formats either; it switches to PCM when it doesn't block the Z12 altogether :frowning_face:

    It's unbelievable that Formuler, with their implementation of the MyTVOnline 3 application, is incapable of providing perfect coordination between hardware and software for modern compatibility! The Z12 Ultra is touted as "the leading and best-tested IPTV receiver on the market." That's an overly optimistic and misleading advertisement :face_with_rolling_eyes::exclamation_mark:Let's hope they provide an update that's on par with the competition.

    I understand you, maby it's coming in an upcoming software update.

    Till then use kodi or so.

    I gonna search on all my 5 providers for thruehd. And test it. I also find out that Exoplayer is from google?? Maby it's google that blocks the sound, cause it's not an certified android version. That's also possible. Let wait what the team says about it.

    And use Kodi so long my friend For the ThrueHD ATMOS.

    Goodday my friend.

  • It's simply a licensing issue in my opinion. They haven't paid the rights for the Dolby TrueHD and DTD-HD formats...

    It is very unlikely that this will be fixed in an update, unfortunately.

    I had the chance to get my hands on a Formuler Z8 yesterday; it had been a while since I last had one. I quickly tried it out on MOL2 with a movie that offered a TrueHD soundtrack, and it worked.

    They must have been less strict about licenses back then...

    I play movie now from vod.

    I have an lg tv with all dolby sound supports.

    I have no soundbar/cinema set to test thruehd.

    I have only Kodi and another user says that when i play a.mkv file with thruehd atmos it's only atmos. Thruehd is only on blu-ray and or m2ts files he said.

    I hope in future a GTV2 with all dolby sounds and hdr types etc. 200dollar/euro. Doesn't matter. I buy one then:smiling_face:

    DTHD doesn't give license to set top boxes.

    The policy has changed over the years - hence why it works on the Z8.

    I believe the problem isn't with the box itself, but with MyTVOnly3, since it works with Kodi. Furthermore, the issue doesn't only affect DTS-HD but also Dolby Digital Plus 7.1, Dolby Atmos 7.1, DTS-HD, and all formats above 5.1!

    Finally, if they don't provide a "license to set top boxes" how do competitors manage to sell boxes that can decode these formats?

    Which competitors are you talking about?

    Because very few boxes offer passthrough of Dolby TrueHD (and DTS-HD) without having other bugs...

    I have a few boxes at home, and it's hard to find the rare gem that works properly with IPTV :winking_face: (except, of course, for the venerable Shi***, which doesn't have the same financial power or development resources as Formuler)

    Sorry to hear that :frowning_face:

    But thank you for the reply :winking_face:
