Follow these checks in Audio Fix →When this guide applies
Known first-ever media pairing with no saved sender or active stream to preserve.
Connection scope: Bluetooth. Symptom: My devices won’t pair or reconnect.
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 this definitely a first media-source pairing, with no saved source history to preserve?
Unknown history stops rather than clears existing devices.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Does compatible BRAVIA Connect already control this correctly set up speaker system?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Does compatible BRAVIA Connect already control this correctly set up speaker system?
App account/network setup is not the same as media registration.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May current playback stop and input change to Bluetooth at low media levels?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown
