Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Known two-channel content in Standard, compatible rears connected and 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 actual incoming programme confirmed two-channel with sound mode Standard?
Unknown content channels or an Atmos programme is a different case.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Are the supplied rear speakers connected and verified with suitable material?
- 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 supplied rear speakers connected and verified with suitable material?
A failed wireless link cannot be fixed by changing an effect.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Do you want processed surround instead of the original Standard stereo presentation?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-2
Do you want processed surround instead of the original Standard stereo presentation?
This changes the sound-field preference; retain the original mode.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Choose Surround with the supplied remote Sound Mode control
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
Choose Surround with the supplied remote Sound Mode control
Do not run ID SET, reset calibration or raise rear levels to the maximum.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Do the intended rear speakers now carry the processed programme?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-4
Do the intended rear speakers now carry the processed programme?
This is upmixing, not proof of discrete surround channels in the original recording.
Look for: Confirm the stated setup or observation. Unknown stops safely.
