Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: 882963

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — Atmos smart soundbar (WiFi + eARC): Bose's flagship soundbar with Dolby Atmos and Bose's AI Dialogue/Immersive processing. Connects to the TV by HDMI eARC and to the network by WiFi (streaming, voice assistants, Bose app). 'No TV sound' is the eARC/HDMI-CEC link; streaming/app is WiFi.
Voice & app: Has built-in voice assistants and uses the Bose Music app for setup and streaming. Pairs with Bose surrounds and the Bass Module 700 wirelessly.
eARC + CEC: For TV audio, use the eARC/ARC port and enable HDMI-CEC on the TV; power-cycle both to fix a lost handshake.

Exact questions

Questions that only have an answer for the Bose Smart Ultra Soundbar

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

My Bose Smart Ultra Soundbar has no sound from the TV.+

Connect it to the TV's HDMI eARC (or ARC) port and turn on HDMI-CEC on the TV (Anynet+/SIMPLINK/Bravia Sync depending on brand), then set the TV's audio output to the ARC/external system. Power-cycle the TV and soundbar to renegotiate the handshake. If the TV has no ARC/eARC, use the optical input instead. Streaming over WiFi through the Bose app still works even if the TV link is down.

Structured depth, not empty permutations
