When this guide applies

Early audio on an actual path where Sync is supported.

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?

Extra audio delay worsens sound already late.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-1

Is Sync actually available for this current TV/HDMI function?

An unavailable or greyed control is not replaced with a guessed setting.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-2

May the current value be retained for a reversible scene comparison?

Use the same scene and restore the old delay if worse.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-3

Select Sync in Sound Control on the supplied remote

Do not change source decoding or TV format settings.

Look for: Perform only the stated operation and confirm whether it was possible.

step-4

Use Up/Down to try a small delay within 0–300 ms

Do not automatically choose the maximum.

Look for: Perform only the stated operation and confirm whether it was possible.

step-5

Is the same scene closer to synchronisation?

A changed number is not a measured timing result.

Possible result

Checks completed — report what happened

Completion is not an automatic solved result. Report your actual outcome; no Audio Review 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 and retain the actual observations

    A required fact or response was not confirmed. Consult the exact product/partner documentation 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, source, partner capability and current state before continuing. Do not guess a menu or interrupt a live session/update.

      insufficient data

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