When this guide applies

Exact Topping DX5 II. The correct source is already connected and selected, headphone-only output is active, but DX5 II itself is confirmed muted. This does not address USB enumeration or a missing input option.

Connection scope: USB audio · Optical digital audio · Bluetooth. Symptom: There is no playback sound.

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.
