Follow these checks in Audio Fix →When this guide applies
Exact Marshall Middleton II. Exact Middleton II is powered with its official app connected by LE. The owner already deliberately completed manufacturer preparation: ordinary phone audio record removed, LE retained, and accepts needing ordinary audio pairing again later. A configured Heddon and its serial digits are identified; Listen to Broadcast(beta) is offered. No call/update is active and both owners accept shared music.
Connection scope: Bluetooth. Symptom: Stereo or party speaker linking 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.
