When this guide applies

Exact IO-8, an appropriate source headphone output and the supplied 3.5 mm lead are available. Playback is paused and source volume is low before plugging in.

Connection scope: Analog line / headphone audio. Symptom: There is no playback sound.

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.

Confirm the analogue output role

The source socket must be a headphone output, not a line input or a USB charging port. Connect the supplied cable to the IO-8’s left-cup mini-jack socket and that source.

Look for: The analogue headphone path is known.

Use passive mode deliberately

The manual allows mini-jack playback with the IO-8 switched off, including when its battery is exhausted. ANC, DSP and sound-mode processing are unavailable in this state.

Look for: Passive analogue mode is intentionally selected.

Control level from the source

Resume quietly and adjust the source’s headphone volume conservatively. In wired analogue modes the level control belongs to the source; do not expect the Bluetooth volume behaviour.

Look for: Observe the same known recording through the passive path.

result

Check the actual result

Does the supplied mini-jack path play from the known headphone output with IO-8 off?

Look for: Confirm the stated setup or visible result. Stop if it is unknown.

Possible result

Checks completed — report the actual outcome

The stated observation was confirmed in this setup. Completion is not an automatic Solved report, a hardware diagnosis or a physical Audio Review test.

steps completed

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Keep the observation for support

    Record the exact model, source, connection and last visible result. Do not reset equipment, open its chassis, bypass protective limits or install firmware to compensate for an unconfirmed result.

    next support

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      Confirm the unknown detail first

      An unknown indication is not a diagnosis. Check the exact instructions or ask the manufacturer before continuing.

      insufficient data

      Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
