Sony BRAVIA Theatre Bar 8 / Bar 9. One expected speaker appears silent; existing setup and partner links already verified.
Connection scope: Device controls / power only. Symptom: Sound plays from only one side.
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.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is the expected speaker a real configured part of this exact system rather than an absent optional accessory?
Do not infer a speaker from marketing channel counts.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Are its setup and any required optional-speaker link already confirmed complete?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Are its setup and any required optional-speaker link already confirmed complete?
An unlinked partner belongs to its connection procedure, not this check.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Can the built-in output check be run safely with listening idle and all on-screen sound-level warnings followed?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Can the built-in output check be run safely with listening idle and all on-screen sound-level warnings followed?
The check emits sound. Stop if the displayed instructions or listening conditions are unsafe or unclear.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-3
Open Settings > Sound Settings > Sound output check
Do not select Sound Field Optimization, reset or an update.
Look for: Perform only the stated operation, then confirm it was possible.

step-4
Run only the displayed speaker-output check following its actual on-screen prompts
Identify which configured speaker responds; do not change cables or raise calibration trims.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Does each requested configured speaker produce its check sound?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-5
Does each requested configured speaker produce its check sound?
If not, retain the exact missing speaker and consult official support. If yes, content/effect routing remains to be checked; this does not claim a physical test by Audio Review.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

Possible result
Checks completed — report the actual result
Completion does not automatically mean the problem is solved. Report what actually happened; no physical test or measured repair is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Stop at the unconfirmed condition
A required setup or response was not confirmed. Retain the actual observation and consult the exact source/partner manual or official support. Do not escalate to a reset, update installation, internal repair or unsafe wiring change.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
A required fact is unknown
Confirm the actual model, connection, partner capability and state before continuing. Do not guess a menu, interrupt an installation or modify a live source by trial and error.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
