When this guide applies

Exact Beam (Gen 2) is already configured in a Sonos system. The TV and Beam are identified and cable roles can be checked safely with playback stopped and levels low.

Connection scope: HDMI / ARC / eARC audio · Optical digital audio. Symptom: There is no playback sound.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

What owners have reported

These are public, self-reported experiences. They help explain the order of checks and the limits of a guide. They are not controlled tests, proof of a cause, a success rate or a substitute for the manufacturer instructions above.

User-reported User-reported — Beam Gen 2 TV-port/setup confusion

An owner reported no TV audio and uncertainty over ordinary HDMI versus ARC and the Beam connection. Replies pointed to the ARC/eARC or optical-adapter path and asked whether system setup had completed.

How this informs the checks: Context for checking model, port roles and existing setup before resets; the manufacturer guide supplies all instructions.

Limits: The thread does not establish a confirmed repair or a general success rate. One reply refers to Gen 1; that reply is not used as Gen 2 instruction authority.

Check the actual result

Does TV audio play through a confirmed ARC/eARC path or the correctly fitted supplied optical-adapter path?

Look for: Confirm the stated setup or visible result. Stop if it is unknown.

Possible result

Checks completed — report the actual outcome

The stated observation was confirmed in this setup. Completion is not an automatic Solved report, a hardware diagnosis or a physical Audio Review test.

steps completed

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Keep the observation for support

    Record the exact model, source, connection and last visible result. Do not reset equipment, open its chassis, bypass protective limits or install firmware to compensate for an unconfirmed result.

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      Confirm the unknown detail first

      An unknown indication is not a diagnosis. Check the exact instructions or ask the manufacturer before continuing.
