Dreambox 900 UHD -IPTV - eac3 - No sound

  • Good morning,


    This is my first topic and I need your help about a problem with the eac3 sound on the Dreambox 900 UHD.


    I bought this machine a week ago and I am still unable to get the sound coming from the French channels (Canal Sat).
    Sound from TV channels like TF1 HD, M6HD are in eac3.


    I am using an IPTV subscription.


    It seems this new machine can decode the eac3 sound as advertised but in my case, I am unable to get it.
    I tried every function's available (downmix AC3 no, eaC3+ to eac3) but it is still not working.


    My question is the following: do you have the same problem when you use this machine with an IPTV subscription ?


    Thank you very much for your answer.


    Regards.

  • How does your Stream-URL look like? If its ending with m3u8 please switch to 1:... instead of 4097:...
    Also are you using the latest available Image on your box? E-AC-3 passthrough was broken in older Image versions.

  • My Stream- URL looks like this (here is an example for M6HD):


    #SERVICE 1:0:1:0:0:0:0:0:0:0:http%3A//maestro.yyyyyxxxxxxxx.com%3A8000/live/xxxxxxx1usr0000/00000000000/6494.ts
    #DESCRIPTION FR: M6 Full HD


    And I am using the last stable image (March 2017) from the Dreambox website.


    I just have the feeling that the eAC3+ doesn't work with a IPTV susbcrition but not sure as I am a newcomer into the world of Dreambox.


    Thank you very much for your help.

  • I tried this image a few minutes ago, also the other one Dreambox released on the 26th of April but unfortunately, it didn't help either.


    Parameters of the audio configuration are:


    AC3 by default=NO
    DOWNMIX AC3=YES
    CONVERT AC3+ TO AC3=CONTROLLED BY HDMI.


    Although I changed the other options (AC3 by DEFAULT=YES, CONVERT AC3+ TO AC3=ALWAYS), I still get the same result, a marvellous picture but no sound :frowning_face:

  • It doesn't matter if its IPTV or DVB-S when you use 1:... it should work.

    Sorry dhwz but I am a newcomer into the world of the IPTV and Dreambox :smiling_face:


    What do you mean exactly by 1:...


    To load the IPTV channels into the Dreambox, I use an address I got from the provider that looks like this:


    wget -O /etc/enigma2/iptv.sh "http://........../etc/enigma2/iptv.sh


    All the TV channels available are stored in the etc/enigma2/ directory with attributes 644

  • Here is a fragment including a TV channel that doesn't work:

  • Seems to be a stream problem, DreamOS can't find the proper audio stream in the transportstream.


    have 1 video stream(s) (0100), and 0 audio stream(s), and the pcr pid is 0100, and the text pid is ffffffff




    FYI: This is no legal IPTV subscription. :winking_face:

  • Thank you for your help, really appreciated.


    I contacted the provider who told me that it's the first time he heard about this problem.


    I used VLCPlayer and a M3U file he sent me and it works perfectly.


    It is possible that the Dreambox is unable to decode the AC3+ ?


    Sure it's not a legal IPTV subscription but where I live, the dish are now prohibited even if you use a legal subscription, it was the only way to get the TV channels
    I am looking for :smiling_face:

    The DDP/AC3+ Audio stream is transmitted with streamtype 0x87... this is not a DVB Streamtype.. but its used in ATSC Standard..


    When you flash the latest unstable firmware from dreamboxupdate.com then you can replace the enigma2 binary with this Version : enigma2.bz2.


    Its bz2 compressed! You must firstly decompress it.


    Or you can do it directly on the dm900 via Telnet oder SSH like this:


    Code
    systemctl stop enigma2 && cd /usr/bin && wget http://ghost.dream-multimedia-tv.de/turner6/enigma2.bz2 && rm enigma2 && bunzip2 enigma2.bz2 && systemctl start enigma2


    Or you have to wait until next update of enigma2 version on the download feed... but its not yet planned.

  • Yes as said AC3+ is now working also with your new example.

    Indeed, what a great day, I started searching the information's about this problem 10 days ago :smiling_face: and you found the solution :smiling_face:


    Time for me to learn how to take a backup of this image, the world of Dreambox is not an easy one :smiling_face:


    Ghost and dhwz, thanks again for your help :smiling_face:
