Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Existing optical path with known supported source audio; no simultaneous HDMI priority.
Connection scope: Optical digital audio. Symptom: There is no playback sound.
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
Is the optical source already connected and confirmed to output a format this soundbar supports?
Unknown partner output or decoder support stops here.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Is no HDMI TV connection currently taking priority over the intended optical path?
- 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 no HDMI TV connection currently taking priority over the intended optical path?
Do not unplug live cables to fit this procedure.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Is the bar currently on another input, with D.IN intended now?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-2
Is the bar currently on another input, with D.IN intended now?
Already selected D.IN with silence needs a different check.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → May the active input change with playback levels initially low?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
May the active input change with playback levels initially low?
The previous source will stop and optical audio may start.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Use Source on the supplied remote to select D.IN
- 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 Source on the supplied remote to select D.IN
Leave source format, partner TV menus and cables unchanged.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Does the intended optical programme now play?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-5
Does the intended optical programme now play?
Correct input selection does not repair an absent optical source signal.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Checks completed — report what happened
