Follow these checks in Audio Fix →When this guide applies
Known current input, available manual A/V Sync; no automatic-TV capability assumed.
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 matching picture movement?
Adding delay worsens audio that already arrives late.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Is Bluetooth Mode not Transmitter, with no native DSD playback active?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

- If Yes / confirmed → May this input timing change with its old value recorded?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
Open Setup > Audio Settings > A/V Sync
Keep the intended source selected.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Try a small manual delay within 0–300 ms in10 ms steps
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-4
Try a small manual delay within 0–300 ms in10 ms steps
Compare the same scene; restore the old value if worse. Do not assume HDMI Auto support.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Is timing closer on that same source?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown
