The ceiling speakers or Dolby Atmos enabled speakers do not output sound, even if the DTS decoder is set to Neural:X.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check the Applicable Products and Categories section of this article before starting these steps.

    Follow the steps below.

    1. It is a specification that Neural:X is not enabled for DTS sources with sampling frequencies between 96 kHz and 192 kHz. As a result, the sound will not be output from the ceiling speakers or Dolby Atmos enabled speakers. Set the sound fields of the receiver to Dolby Surround. If you set the sound fields of the receiver to Dolby Surround, then sound will output from the ceiling speakers or Dolby Atmos enabled speakers.

    2. Try either of the following to check the HDMI setting of the connected HDMI device (such as a Blu-ray Disc player):

      • Change the audio channel of the disc or content to audio output other than DTS such as LPCM or Dolby.
      • Set the audio output setting of the HDMI device to LPCM.
      NOTE: For how to change the settings, refer to the manual of the HDMI device

    What is Neural:X?
    Neural:X is the latest upmixing technology from DTS that expands the stereo 5.1 channel and 7.1 channel to multi channels. It can be played on the multi channel speaker including height speakers.
