Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
TV Audio automatic eARC switching enabled; manual source selection preferred.
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
Does the unwanted change specifically switch to display eARC audio?
A Bluetooth reconnection or remote-source command is a different trigger.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Is TV Audio currently enabled in HDMI Settings?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-1
Is TV Audio currently enabled in HDMI Settings?
Unknown or already disabled state does not justify another change.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Do you want TV audio to require manual DISPLAY selection?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-2
Do you want TV audio to require manual DISPLAY selection?
Disabling automatic selection changes normal TV convenience; retain the original setting.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Disable only HDMI Settings > TV Audio
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
Disable only HDMI Settings > TV Audio
Leave CEC Control, eARC volume control, HDMI Bypass and output routing unchanged.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → During the same normal TV activity, does the chosen source remain selected?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-4
During the same normal TV activity, does the chosen source remain selected?
The menu change alone does not prove a partner fault or a firmware cause.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Checks completed — report what happened
