Follow these checks in Audio Fix →When this guide applies
Exact JBL Boombox 4. Audio must already work; this checks app discovery, not Bluetooth source pairing. Bluetooth source context; no reset or saved-pairing deletion is prescribed.
Connection scope: Bluetooth. Symptom: The control app cannot find my device.
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.
