Follow these checks in Audio Fix →

When this guide applies

Output currently SPDIF but the documented partner expects ADAT; clock/rate already compatible.

Connection scope: Optical digital audio. Symptom: Sound goes to the wrong output.

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 step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Does the exact connected partner documentation require ADAT optical input?

TOSLINK shape alone does not distinguish ADAT from SPDIF.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-1

Are both devices already documented compatible at the selected sample rate and clock arrangement?

Unknown partner format/rate/clock stops rather than assumes 8 channels at every rate.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-2

Is the official driver Settings dialog available for this connected interface?

Standalone or unknown host-control availability needs its own exact procedure; do not guess a software menu.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-3

Is Optical Out currently SPDIF, and may it change with playback/recording stopped?

The optical stream will be interrupted. Retain the original format.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-4

Set Optical Out to ADAT in the driver Settings

Use the actual output-format control; the optical input detects format automatically.

Look for: Perform only the stated operation, then confirm whether it could be completed.

step-5

Does the known partner indicate the intended ADAT input lock and receive its routed channels?

A menu change alone is not proof of partner lock or channel routing.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

Possible result

Checks completed — report what happened

Completion is not an automatic solved result. Report solved, partly helped, did not help or could not follow based on your actual observation. No Audio Review physical test is claimed.

steps completed

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

    Possible result

    Keep these observations for official support

    A required prerequisite or response was not confirmed. Stop this sequence and use the exact model and partner documentation. Do not escalate to a factory reset, firmware installation, internal repair or unsafe wiring change.

    next support

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

      Possible result

      A required fact is unknown

      Confirm the exact model, connection, partner capability and current control state before continuing. Do not guess settings or operate an updating product.

      insufficient data

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