Known current HDMI path; audio precedes picture and actual app timing control is available.
Manufacturer-documented Reviewed 2026-11-09 · Revision 2
Follow these checks in Audio Fix →When this guide applies
Known current HDMI path; audio precedes picture and actual app timing control is available.
Connection scope: HDMI / ARC / eARC audio. Symptom: Sound and picture are out of sync.
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
Does sound arrive before the matching picture movement?
Additional audio delay can worsen sound already late.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is A/V Sync actually available for the current HDMI playback path?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is A/V Sync actually available for the current HDMI playback path?
Do not replace an absent control with another Sony model menu.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May the old timing value be retained before a small reversible trial?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
May the old timing value be retained before a small reversible trial?
Compare the same scene and preserve the original preference.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Increase the available A/V Sync audio delay slightly within the displayed choices
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Increase the available A/V Sync audio delay slightly within the displayed choices
Do not assume an undocumented range or change partner TV processing.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Is the same scene now closer to synchronisation?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
Is the same scene now closer to synchronisation?
A changed value is not a measured timing result.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

- If No → Stop at the unconfirmed condition

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.
