When this guide applies

Exact Yamaha R-N800A. Verified optical cable and known working downstream route; no HDMI ARC on R-N800A. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Optical digital audio. 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.

Checks and possible outcomes

Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

scope

Confirm the exact setup

The optical cable and receiving port are confirmed, the source’s actual digital-format setting is known and the owner accepts a source-format change.

Look for: Choose only a detail you can confirm.
