Follow these checks in Audio Fix →When this guide applies
Exact Accentum True Wireless with a Bluetooth source. The earbuds are connected but silent and another source may hold the audio connection. Confirm the first source currently shows an active headphone connection before continuing; a saved pairing entry alone is insufficient. Reversible checks only; no factory reset or pairing-list deletion.
Connection scope: Bluetooth. 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.

Accept disconnecting this source’s Bluetooth accessories?
The next action turns Bluetooth off on the other source device. This temporarily disconnects all its Bluetooth accessories, including any keyboard, mouse, watch or audio device; it also interrupts Bluetooth calls or media there. Pairing records are retained. Continue only if you can safely operate that source without those accessories and accept the interruption. You can turn Bluetooth back on after the comparison.
Look for: Confirm this state explicitly before continuing.
- If I accept the temporary disconnections → Disconnect the other source temporarily
- If Keep Bluetooth on → Use model and source support
- If I do not know / cannot check → More information is needed
