Samsung HW-Q990F: add a small supported Sync delay for audio arriving before the TV picture
Samsung HW-Q990F — add a small supported Sync delay for audio arriving before the TV picture. Confirm the actual setup and observed response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →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.
- If Yes / confirmed → Is Sync actually available for this current TV/HDMI function?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

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.
- If Yes / confirmed → May the current value be retained for a reversible scene comparison?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

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.
- If Yes / confirmed → Select Sync in Sound Control on the supplied remote
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

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.
- If Yes / confirmed → Use Up/Down to try a small delay within 0–300 ms
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

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.
- If Yes / confirmed → Is the same scene closer to synchronisation?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-5
Is the same scene closer to synchronisation?
A changed number is not a measured timing result.
Look for: Confirm the stated setup or observation. Unknown stops safely.

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.
