Sure, here's a two-paragraph answer to the question Why does my receiver indicate Dolby Atmos DTS X playback but the new 4K Blu-ray player indicates lossless audio only?

It's important to understand that Dolby Atmos and DTSX are both object-based audio formats that aim to create a multidimensional sound experience. Unlike traditional surround sound systems that operate on a single horizontal plane, these formats allow for a more immersive experience by adding overhead speakers to create a three-dimensional sound field. While Dolby Atmos requires additional overhead speakers to be installed, DTSX can utilize the existing speakers in a 5.1 or 7.1 channel surround sound system.

When playing a DTS MA 7.1 soundtrack with a Blu-ray player set to auto audio, the receiver may indicate DTS HD Neural X, which is an upgrade from DTS MA. This is because DTSX is a next-generation surround sound format designed to compete against Dolby Atmos. It's important to note that DTSX is an object-based audio codec that aims to create a multidimensional sound that moves around you like it would in real life. Therefore, it's not a bad thing that the receiver defaults to DTS NeuralX mode when playing a DTS MA 7.1 soundtrack. In fact, it's an upgrade that allows for a more immersive sound experience.
