Follow these checks in Audio Fix →When this guide applies
LG S90TR / S95TR. Known two-channel programme with Surround Off; actual speaker links already working.
Connection scope: Device controls / power only. Symptom: An option or codec is missing.
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 incoming programme confirmed two-channel, with the intended surround presentation absent?
A native channel failure or unknown source format is different.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Are the intended supported speakers already connected and known working?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Are the intended supported speakers already connected and known working?
Changing an effect does not repair a missing wireless link.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is Surround explicitly Off, and do you want processed surround rather than the present presentation?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Is Surround explicitly Off, and do you want processed surround rather than the present presentation?
Retain the old preference; upmixing does not add original discrete recording channels.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-3
Press Settings on the supplied remote
Do not start pairing or hold an unrelated hardware control.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Use Left/Right to choose Surround
- If I could not do this → Stop at the unconfirmed condition

step-4
Use Left/Right to choose Surround
Keep the existing source and levels unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Use its Up/Down control to set Surround On and confirm LED1 blinking white
- If I could not do this → Stop at the unconfirmed condition

step-5
Use its Up/Down control to set Surround On and confirm LED1 blinking white
Stop if the indication differs; do not keep blindly toggling.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Is the intended surrounding presentation now audible on that same programme?
- If I could not do this → Stop at the unconfirmed condition

step-6
Is the intended surrounding presentation now audible on that same programme?
Not every driver must reproduce every moment of a programme.
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.
