No. This TV does not support the DTS (Digital Theater Systems) audio format. If your TV receives a DTS signal via HDMI, it will not transfer this signal via its HDMI ARC (HDMI Audio Return Channel) or the 'DIGITAL AUDIO OUT´ (SPDIF) connection.
In order to hear the DTS audio signal, you need to connect the digital audio output of the source device to an external amplifier.
