TV app limitations
Built-in apps and external players do not always expose the same audio path to eARC.
eARC Soundbar Audit Dubai
The return channel needs proof.
Cinema Machina verifies whether the TV, source device, soundbar or AVR, HDMI chain, and app or player route are actually handing off the intended audio format.
What usually fails
Soundbar Atmos can fail quietly.
HDMI control conflict
CEC, firmware, and input routing can change the format before the soundbar sees it.
False format confidence
A logo on-screen does not prove the expected audio object data reached the bar.
What Cinema Machina verifies
The soundbar is only one link.
We evaluate the complete route that feeds the soundbar rather than treating the soundbar as the whole system.
- TV audio route and eARC mode
- Source-device output behavior
- HDMI cable and port path
- Soundbar format reporting
- Disc-grade and app-based source comparison
When to book an audit
Book when the room sounds smaller than the spec sheet.
- Atmos appears inconsistent between apps and local playback.
- A Samsung Q990C or comparable bar does not report the expected format.
- Dialogue, height effects, or bass impact changes by source.
- You need a clean audio route before expanding the system.
