Follow these checks in Audio Fix →When this guide applies
Supported headphones already play the same audio through SimpleSync, with the bar currently unmuted.
Connection scope: Bluetooth. Symptom: Sound goes to the wrong output.
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
Are verified compatible headphones already connected through SimpleSync and audibly playing the same programme?
A phone-source connection or silent unverified partner has another path.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-2
Do you want private headphone listening while keeping the previous comfortable headphone level?
Only the bar output is to stop; retain the normal listening preference.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
