Follow these checks in Audio Fix →When this guide applies
Exact FiiO K9 AKM. This exact K9 AKM has no prior audio pairing and is available for ordinary first-use pairing. Front PO is already selected and the physical unit is unambiguous.
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
This exact K9 AKM has no prior audio pairing and is available for ordinary first-use pairing. Front PO is already selected and the physical unit is unambiguous.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept switching to BT media?
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

Accept switching to BT media?
Changing input interrupts current media. Continue only outside calls/recordings with agreement to pause and lower headphone volume first. No pairing record is erased.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause any existing media
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required

Pause any existing media
Pause media and keep front headphone volume low; rear outputs are unused.
Look for: Observe the named indication or available control; stop if absent.
- If I completed this check → Select BT normally
- If I cannot complete this → Continue with source and model support
- If I cannot determine this → More information is required

Select BT normally
Use INPUT to select BT without holding INPUT. Holding it is a separate clear-pairing operation and must not be used.
Look for: Observe the named indication or available control; stop if absent.

Select the exact K9 AKM
On the intended nearby source choose K9 AKM in the Bluetooth list. If absent or already connected elsewhere, stop instead of clearing pairings.
Look for: Observe the named indication or available control; stop if absent.
