DTS support varies across players, televisions and receivers. ATV accepting video does not guarantee it can decode or forward every DTS variant. Check the exact model and format, then use a legitimate supported alternative or local decoding where the player provides it. Read the precise DTS variant and the support for the exact input route. A receiver's ability to decode one DTS-family format directly does not establish that the television can decode it, pass it through or preserve it across its return-audio connection.
Read variant details
DTS family formats can have different requirements. Inspect the track information for the actual format rather than stopping at the broad DTS family label. Core, extension and object-based arrangements can involve different requirements, and documentation should identify what the chosen player supports. Keep the source resolution and container separate from the audio question. If the app offers a supplied compatible alternate track, test it without changing the physical route so the comparison isolates the audio-format requirement more clearly.
Check the return path
TV-to-soundbar transport may differ from direct receiver input. Check whether the source connects directly to the receiver or reaches it through the television. The TV's internal playback, external-input passthrough and audio return are separate capabilities. A receiver accepting the format on a direct input can still remain silent if an upstream stage cannot send it. Consult the exact TV and receiver manuals for that route, and use the receiver's actual received-format information where available rather than relying on a front-panel effect label.
Use supported settings
Do not force an unsupported bitstream. Do not force an unsupported bitstream just because a format option appears in software. Compare documented source decoding or an authorized alternate track if available, noting any change in channel layout. If a direct supported receiver connection works, consider the video implications and household control arrangement before retaining new wiring. Keep volume moderate while switching, and report the precise variant, app version and route if support is needed to investigate a repeatable failure.

An example to work through
A receiver handles a DTS track directly, while the TV return path does not forward that variant. The receiver plays the track on a direct supported input but not when the TV sits between source and receiver. That narrows the question to the television's handling and return route, rather than proving the receiver's DTS decoder is unavailable or that the stream contains no audio.
Questions about this topic
DoesDTS on a receiver guaranteeTV support?
No. The TV's decode and passthrough capabilities need their own model-specific confirmation.
Can a cable add a decoder?
No. A transport cable cannot provide a codec implementation that an endpoint lacks.
