Hi all, This will probably require a Marantz owner/user to answer if possible please! Basically no sound from extra speakers over 5.1 with Atmos Marantz SR7012 - latest firmware Sony UBP-X800 - latest firmware 6.1.2 setup (5.1 plus top middle left, top middle right, 1 x Surround Back speaker) Atmos sound issue: I like to think I'm fairly technical but I may have missed something here, hope anyone can help: No sound comes from my TML or TMR or SB speakers when setting the sound to Dolby Atmos. I get 5.1 basically and it sounds fine. When I set it to Dolby TrueHD/Neural:X I get the sound from everywhere no problem and it sounds great but this is basically 5.1 TrueHD with the extra channels processed out of that for my heights and SB channel. The receiver shows it's receiving Dolby Atmos and the speakers that it should be playing sound through are showing as highlighted but nothing comes out of the extra speakers I have which is just really odd. I've tried different discs and even a different Blu-Ray player! I even set the TML and TMR speakers as upward firing Dolby specific height surround speakers (turned my SB speaker off too) in the menus and they tested fine but again, no sound from those 2 speakers with the Atmos setting when playing the discs! Do I have to settle for Dolby TrueHD with Neural:X...it sounds better than Atmos from 5.1 speakers by far but I'd rather have Atmos from 6.1.2 to at least hear what it sounds like and have the choice!! Thanks for any help here... Rob.
