Follow these checks in Audio Fix →When this guide applies
One supplied front speaker is red while center is awake; no optional subwoofer/rears configured.
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.
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 supplied front speaker with its power indicator red while the center is awake?
An absent source channel, optional rear or normal standby state is different.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Are both supplied front speakers safely installed/powered, with their LINK controls identifiable?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Are both supplied front speakers safely installed/powered, with their LINK controls identifiable?
Do not open units, move wall mounts or modify mains.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Are no optional subwoofer/rear speakers currently configured?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Are no optional subwoofer/rear speakers currently configured?
The documented remote sequence also disconnects optional links; preserve those installations rather than guessing how to restore them.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you accept disconnecting and reconnecting both supplied front links, including a currently working side?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown
