Follow these checks in Audio Fix →When this guide applies
Sennheiser AMBEO Soundbar Plus / Sennheiser AMBEO Soundbar Mini. Known HDMI return/direct path, audio ahead of picture; actual Input Lip sync control 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 the audio arrive before the matching picture movement?
Adding delay can worsen audio already behind the picture.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is Input > Lip sync actually available for this identified HDMI input?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is Input > Lip sync actually available for this identified HDMI input?
Do not substitute a Max or different-brand menu for a control that is absent.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May the old value be retained before a small reversible timing comparison?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
May the old value be retained before a small reversible timing comparison?
Compare the same scene, keeping source/TV processing unchanged.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Increase the displayed Smart Control Input > Lip sync delay slightly
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Increase the displayed Smart Control Input > Lip sync delay slightly
Use only the available choices; no undocumented numerical range is assumed.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Is that 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 that same scene now closer to synchronisation?
Restore the old value if worse; this is not a measured timing result.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

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.
