When this guide applies

Exact WiiM Amp Pro. Only the combined Optical/HDMI control explicitly visible and On; user accepts losing automatic selection for both of those inputs. Only normal external user controls; no reset, firmware installation, internal repair, mains alteration or earth lifting.

Connection scope: Optical digital audio · HDMI / ARC / eARC audio. Symptom: Switching between devices isn’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.
