Sonos Arc Ultra Soundbar with Dolby Atmos - Black- All-new acoustic architecture with Sound Motion technology fills every inch of the room and precisely place sounds all around you
- Unparalleled 9.1.4 spatial audio experience with Dolby Atmos
- Ultra-clear dialogue plus Speech Enhancement, powered by AI, detects the human voice to clarify every word
- Elegant design looks great in your home and won’t distract from your entertainment

The Arc Ultra must be set up with the Sonos app before it can play TV audio. Complete this setup before adding a Sub or rear surrounds; add compatible components afterward through the app.
Choose the right TV connection
Use HDMI ARC or eARC for the standard TV connection. The TV must have an ARC/eARC port to use it. Optical is a fallback option for some Sonos home-theater setups, using an optical audio adapter, but it has important limits for the Arc Ultra experience.
| Connection | Audio formats and Atmos | TV control |
|---|---|---|
| HDMI ARC | Supports many Dolby Digital Plus Atmos streams. It does not carry lossless Dolby Atmos using Dolby TrueHD. | Supports HDMI-CEC features; a TV remote works automatically with HDMI ARC. |
| HDMI eARC | Required for lossless Dolby Atmos using Dolby TrueHD. The TV and source also need to support the format. | Supports HDMI-CEC features when enabled on the TV. |
| Optical audio adapter | Does not provide Dolby Atmos. | Does not provide HDMI-CEC or TV power voice commands. Set up the remote in the Sonos app. |
Sonos’s Arc Ultra setup guidance specifies the included HDMI cable; it does not establish that an optical adapter is included. Do not assume one is in the box. Check the TV manual for port and setting details.

Get Dolby Atmos and verify the signal
Atmos depends on more than the soundbar: the TV, source device, specific title, and streaming-service plan can all affect availability. A service that offers Atmos does not necessarily deliver it for every program.
HDMI ARC can carry many Atmos streams encoded in Dolby Digital Plus. For lossless Atmos using Dolby TrueHD, eARC is required. Some devices, including Apple TV, pass Atmos using Dolby MAT, so the format shown by the Sonos app can reflect how the source device delivers audio.
