Original SR/SL rear slowly blinks while the awake bar otherwise operates; its current stored link may be cleared.
Connection scope: Device controls / power only. Symptom: Sound plays from only one side.
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.
What owners have reported
These are public, self-reported experiences. They help explain the order of checks and the limits of a guide. They are not controlled tests, proof of a cause, a success rate or a substitute for the manufacturer instructions above.
User-reported AX5125H Rear Speaker Noise?
Owners describe rear-speaker noise while the main bar remains clear across several sources; the cause and any firmware outcome are unverified.
How this informs the checks: Context only: rear noise is not proof of an unlinked speaker. This flow requires the actual documented slow-blinking link state and does not adopt forum level boosts or firmware suggestions.
Limits: User-reported public account only. Exact setup, diagnosis and outcome are not independently verified; no prevalence or physical test is claimed.

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 affected unit the original SR or SL rear with its link indicator slowly blinking while the main bar is awake?
A steady linked speaker with noise or programme silence has another path.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is that original unit already safely installed/powered, with actual SOURCE and its rear PAIR controls identified?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is that original unit already safely installed/powered, with actual SOURCE and its rear PAIR controls identified?
Do not access a wall mount, touch mains or open electronics.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you accept clearing this affected rear current pairing record and registering it with this intended bar again?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Do you accept clearing this affected rear current pairing record and registering it with this intended bar again?
Stop if an existing required link must be preserved or its identity is uncertain.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May current listening pause for the documented link attempt, with no installation running?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
May current listening pause for the documented link attempt, with no installation running?
Keep levels low. This is not a promise that every other speaker is tested.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Hold SOURCE on the main unit or supplied remote for three seconds until SW Pairing appears
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
Hold SOURCE on the main unit or supplied remote for three seconds until SW Pairing appears
Use SOURCE rather than the two-second phone Bluetooth control.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Hold PAIR on only the affected original rear for two seconds until its indicator blinks quickly
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-5
Hold PAIR on only the affected original rear for two seconds until its indicator blinks quickly
This is the accepted deletion/re-pair operation; do not operate an unaffected nearby unit.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Does the affected Pair indicator become constant, with the main display reporting SW IN?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-6
Does the affected Pair indicator become constant, with the main display reporting SW IN?
Stop on failure. No repeated clears, power-cord procedure or firmware installation follows.

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.
