Follow these checks in Audio Fix →When this guide applies
Exact iFi iDSD Diablo 2. Bluetooth mode is selected, fewer than8saved sources are positively known, front conventional headphones only and rear 4.4 mm unused. You want a new audio source.
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 scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
scope
Confirm the model and connection
Bluetooth mode is selected, fewer than8saved sources are positively known, front conventional headphones only and rear 4.4 mm unused. You want a new audio source.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Confirm spare pairing capacity and accept interruption?
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

Confirm spare pairing capacity and accept interruption?
The manual specifies8saved devices. Continue only with fewer than8positively known and agreement to interrupt current media. Unknown memory count or unit identity must stop; do not clear pairings.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause current media
- If No / leave this unchanged → Continue with source and model support
