Follow these checks in Audio Fix →When this guide applies
Exact FiiO K17. The original K17 screen is too bright. This local display adjustment does not depend on the connected audio source.
Connection scope: Device controls / power only. Symptom: Buttons, touch controls or wear detection aren’t working.
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.
