Follow these checks in Audio Fix →When this guide applies
Read-only System Info; no update installation or example version treated as current.
Connection scope: Device controls / power only. 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
