Follow these checks in Audio Fix →When this guide applies
App-connected status observation.
Connection scope: Bluetooth. Symptom: I need to check firmware update requirements.
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 this exact speaker connected in Marshall Bluetooth app?
Working audio alone does not prove the app link.
Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
- If Yes / this check is completed → Open About for this speaker
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-1
Open About for this speaker
Read its displayed firmware status.
Look for: Perform only the stated check, then confirm whether it could be completed.
- If Yes / this check is completed → Does About explicitly report a known state?
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-2
Does About explicitly report a known state?
Unknown remains unknown; no latest version is hardcoded here.
Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
- If Yes / this check is completed → Record that status for support
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-3
Record that status for support
If an update is offered, follow separate official readiness instructions later. This does not start an update or claim repair.
Look for: Perform only the stated check, then confirm whether it could be completed.
- If Yes / this check is completed → Checks completed — report your outcome
- If No / this cannot be confirmed → Keep the observation for manufacturer support
