Follow these checks in Audio Fix →When this guide applies
Pure Direct On blocks native processing; valid unchanged Auto Calibration and an already eligible 360SSM layout/mode are confirmed.
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 Pure Direct explicitly On while the wanted feature is 360 Spatial Sound Mapping?
An unknown or already Off state needs another explanation.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is valid Auto Calibration already stored for the unchanged actual layout of at least 4.0.0 channels?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is valid Auto Calibration already stored for the unchanged actual layout of at least 4.0.0 channels?
No measurement or speaker-layout change is performed here.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Are headphones absent and Bluetooth Transmitter inactive, with an already supported A.F.D. or A.F.D. Movie field selected?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Are headphones absent and Bluetooth Transmitter inactive, with an already supported A.F.D. or A.F.D. Movie field selected?
Unknown eligibility or another mode stops rather than forces availability.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you want normal processing instead of the current Pure Direct preference?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Do you want normal processing instead of the current Pure Direct preference?
The display and sound processing can change; retain the previous state and comfortable level.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Set Sound Effects > Pure Direct to Off
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
Set Sound Effects > Pure Direct to Off
Leave calibration, speaker pattern, equalizer and source format unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Is the already eligible 360SSM control now available for this setup?
- 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
Is the already eligible 360SSM control now available for this setup?
Availability is not proof of a measured spatial improvement or that an unconfigured speaker exists.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

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.
