Manufacturer-documented Reviewed 2026-11-09 · Revision 2
Follow these checks in Audio Fix →When this guide applies
Signed-in compatible app works while awake on the same network; failure only from standby.
Connection scope: Wi-Fi / Ethernet network audio. Symptom: The control app cannot find my device.
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 signed-in compatible app already control this speaker system while awake on the same known network?
Unknown account/network state belongs to initial setup.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is Network/Bluetooth Standby explicitly Off?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is Network/Bluetooth Standby explicitly Off?
Do not toggle an unknown or already On preference.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you accept retained network standby operation and its power tradeoff?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Do you accept retained network standby operation and its power tradeoff?
Keep ordinary standby if the lower-consumption choice was intentional.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Set Settings > System Settings > Network/Bluetooth Standby to On
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Set Settings > System Settings > Network/Bluetooth Standby to On
Leave Auto Update, account registration and network addresses unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → May ordinary standby be tested with no active programme or update?
- If I could not do this → Stop at the unconfirmed condition

step-4
May ordinary standby be tested with no active programme or update?
The current awake session will stop.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Put the speaker system into normal standby
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-5
Put the speaker system into normal standby
Do not disconnect center/front-speaker mains.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Send ordinary power-on from the already verified app
- 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
Send ordinary power-on from the already verified app
Use the same network/account route.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Does the intended speaker system wake through that app command?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-7
Does the intended speaker system wake through that app command?
A saved preference alone is not proof of network discovery.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

- If No → Stop at the unconfirmed condition

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.
