Follow these checks in Audio Fix →When this guide applies
LG S90TR / S95TR. Current input is unrelated to TV; known configured ARC/eARC path.
Connection scope: HDMI / ARC / eARC 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 existing cable already between this bar HDMI TV (eARC/ARC) and the TV documented return connector?
An unknown or ordinary TV HDMI input stops before changing source.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Are the exact TV speaker-output and required ARC/eARC controls already confirmed in its manual?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Are the exact TV speaker-output and required ARC/eARC controls already confirmed in its manual?
Do not infer a TV menu or eARC support from an HDMI connector alone.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is LED1 currently showing an unrelated input rather than the white return-audio indication?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Is LED1 currently showing an unrelated input rather than the white return-audio indication?
An already selected return input with silence needs a different check.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May current playback switch to TV with listening levels initially low?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
May current playback switch to TV with listening levels initially low?
The existing source will stop and television sound may start immediately.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Use Function on the supplied remote until LED1 is white for TV return
- If No → Stop at the unconfirmed condition

step-4
Use Function on the supplied remote until LED1 is white for TV return
Leave television menus, CEC, source format and cables unchanged.
Look for: Perform only the stated operation, then confirm it was possible.

Does the intended television programme now play through the bar?
Input selection cannot establish an absent partner return capability.
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
