Follow these checks in Audio Fix →When this guide applies
Exact FiiO KA11. KA11 audio works but its indicator is dark and the Android app control connection already works. This is a disabled-light setting rather than a USB audio failure.
Connection scope: USB audio. 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.
