When this guide applies

Exact IO-8 plays through its mini-jack cable while switched off. The question is why active processing is absent, not whether the passive cable carries sound.

Connection scope: Analog line / headphone audio. Symptom: An option or codec is missing.

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.

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

  • Manufacturer-documented DALI IO-8 original manufacturer manual (Richer Sounds copy) ↗Original DALI IO-8 manual pp.8–9,14–15 — With the headphone switched off and the mini-jack path playing, the manual defines this as analogue wired passive mode. ANC, transparency, DSP and the Hi-Fi/Bass sound-mode processing require active operation. Their absence in passive mode is documented rather than proof of a failed button. Continue passive listening if that is intended. To use active features, first charge and use the manual’s active mode at a safe source level; do not assume passive battery-free playback also powers ANC.Exact models: DALI IO-8.

Identify the current mode

With the headphone switched off and the mini-jack path playing, the manual defines this as analogue wired passive mode.

Look for: Passive mode is positively identified.

Compare available functions

ANC, transparency, DSP and the Hi-Fi/Bass sound-mode processing require active operation. Their absence in passive mode is documented rather than proof of a failed button.

Look for: The missing functions are explained by passive operation.

Keep the choice explicit

Continue passive listening if that is intended. To use active features, first charge and use the manual’s active mode at a safe source level; do not assume passive battery-free playback also powers ANC.

Look for: The distinction between passive playback and active processing is retained.

result

Check the actual result

Is the headphone in passive mode and are the absent active functions explained by that mode?

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

Possible result

Documented connection limitation

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

documented limitation

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.
