When this guide applies

TV Auto Switch is currently Yes and a deliberate manual source should remain selected.

Connection scope: 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.

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

Is the unexpected takeover specifically to the TV (eARC) input?

A Bluetooth, streaming or remote-command source change is a different trigger.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-1

Is that TV input Auto Switch currently Yes?

An unknown or already No state does not justify changing it.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-2

Do you want TV source selection to become manual?

Future TV audio may require selecting TV (eARC) explicitly. This is not a CEC reset.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-5

On the same normal TV activity, does the intended source remain selected?

A menu change alone does not establish the actual trigger or repair a partner fault.

Look for: Confirm the stated setup or observation. Unknown stops safely.
