If a DTS/DTS-HD 2.0 96/24 disc is played, DTS Neural:X is not a selectable sound mode. A DTS 5.1/7.1/X 96/24 disc would also be locked out of the Neural:X sound mode. I'm not sure what is going on with those two discs exactly and I do not have them myself or a Denon receiver at the moment to try and replicate the issue. My Onkyo does not have a DTS 96/24 limitation and still has multiple sound modes for all DTS signals while most DTS modes have been dropped from newer Denon and Onkyo models for just DTS or DTS-HD with Denon having up mixer limitations for DTS 96/24 signals.
