Manufacturer-documented Reviewed 2026-11-09 · Revision 1

When this guide applies

Sony BRAVIA Theatre Bar 8 / Bar 9. DTS Dialog Control unavailable on current material; a known compatible owned track is available.

Connection scope: HDMI / ARC / eARC audio. Symptom: An option or codec is missing.

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 unavailable setting specifically DTS Dialog Control in Sound Settings?

Voice mode, Voice Zoom and overall volume are separate features.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → Do the actual media/player documents confirm a track authored for DTS:X dialogue control?
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-1

Do the actual media/player documents confirm a track authored for DTS:X dialogue control?

A generic DTS:X logo alone does not establish this metadata.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → Does the already working HDMI source path support that exact track format?
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-2

Does the already working HDMI source path support that exact track format?

Unknown player/TV pass-through or codec capability stops here.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → May playback switch to that authorised known compatible track at a comfortable level?
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-3

May playback switch to that authorised known compatible track at a comfortable level?

This changes the current programme; do not download an unapproved test file.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → Select the verified track using the actual player/media documented control
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-4

Select the verified track using the actual player/media documented control

No universal player menu or TV setting is assumed.

Look for: Perform only the stated operation, then confirm it was possible.

If I completed this → Inspect Settings > Sound Settings > DTS Dialog Control during that track
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

Inspect Settings > Sound Settings > DTS Dialog Control during that track

Do not force a greyed setting or alter unrelated processing.

Look for: Perform only the stated operation, then confirm it was possible.

If I completed this → Is the control now available for the compatible track?
If I could not do this → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-6

Is the control now available for the compatible track?

Availability is not proof of measured dialogue quality; retain actual source/format information if support is needed.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → Checks completed — report the actual result
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is 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.
