Yamaha RX-A6A: delay audio that arrives before the picture
Yamaha RX-A6A: delay audio that arrives before the picture. Check prerequisites and the actual response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Known HDMI source; per-input Lipsync already enabled.
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 audio arrive before the corresponding picture?
Adding delay cannot advance audio already late.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Is Sound > Lipsync > Delay Enable already confirmed enabled for this input?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
Is Sound > Lipsync > Delay Enable already confirmed enabled for this input?
An unknown or disabled correction prerequisite must be checked before this manual adjustment.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → May this input timing value be changed temporarily?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
May this input timing value be changed temporarily?
Record its original value for restoration; no Auto Lip Sync support is assumed for the TV.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Open Sound > Lipsync > Adjustment
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Open Sound > Lipsync > Adjustment
Stay on the intended source.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Increase delay by a small amount within0–500ms
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Increase delay by a small amount within0–500ms
Compare the same scene; return to the previous value if worse.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Is timing actually closer in that same scene?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-5
Is timing actually closer in that same scene?
Do not claim a fix solely because a number changed.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

Possible result
Checks completed — report what happened
Completion is not an automatic solved result. Report solved, partly helped, did not help or could not follow based on your actual observation. No Audio Review physical test is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Keep these observations for official support
A required prerequisite or response was not confirmed. Stop this sequence and use the exact model and partner documentation. Do not escalate to a factory reset, firmware 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 exact model, connection, partner capability and current control state before continuing. Do not guess settings or operate an updating product.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
