Follow these checks in Audio Fix →

When this guide applies

Existing configured TV ARC/eARC path, not a directly connected player.

Connection scope: HDMI / ARC / eARC 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 step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Does this exact TV and port definitely support ARC or eARC?

Check the TV manual; HDMI alone does not establish return-audio capability.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-1

Is the installed cable at receiver HDMI OUT MAIN marked ARC?

Inspect labels without moving live cables; a SUB/zone output does not replace MAIN return audio.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-2

Are required receiver return-audio and TV settings already confirmed?

Unknown partner settings stop here; do not blindly toggle CEC or infer an unsupported TV menu.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-3

May current receiver playback switch to the TV source?

The current listening source will stop.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-4

Select TV using the normal input selector

Use the TV app/tuner path rather than the directly connected player selector.

Look for: Perform only the stated operation, then confirm whether it could be completed.

step-5

Does the intended TV programme now play?

Observe the actual response at a comfortable level. Correct port labels alone are not playback proof.
