Follow these checks in Audio Fix →When this guide applies
Main FRONT A system, no headphones or alternative FrontB configuration.
Connection scope: Device controls / power only. 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
Does the display explicitly show SPK OFF?
An unknown state or an already selected speaker system needs another check.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Are the intended front speakers known connected to FRONT A with no configured FrontB/bi-amp/Zone 3 alternative?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-1
Are the intended front speakers known connected to FRONT A with no configured FrontB/bi-amp/Zone 3 alternative?
Do not select parallel or reassigned outputs by guesswork.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Are headphones disconnected and listening levels initially low?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-2
Are headphones disconnected and listening levels initially low?
Speaker selection is unavailable with headphones connected and may restore sound immediately.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Use SPEAKERS on the unit to select SPA
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
Use SPEAKERS on the unit to select SPA
Observe SPA rather than SPB or SPA+B; do not change speaker assignments.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Does the intended main speaker system now play comfortably?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-4
Does the intended main speaker system now play comfortably?
A display change does not prove a source signal or speaker connection healthy.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Checks completed — report what happened
