When this guide applies

Exact M10 V3 and the external port label are identified. The question concerns a computer USB-audio connection, not playback from a USB flash drive.

Connection scope: USB 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

Read the actual port labels

The SERVICE USB port and switch are for servicing only. The consumer USB port is documented for a FAT32/NTFS storage drive. Do not use the service port as an experimental audio input.

Look for: The service and consumer storage roles are separated.

Compare with the manual’s USB operation

The consumer USB instructions describe detecting drive files and selecting Library or USB in BluOS. They do not describe a computer USB-DAC endpoint.

Look for: The requested computer-DAC role is not the documented storage role.

Keep an appropriate documented source path

Use an already supported optical, coaxial, analogue or network source as appropriate to your system. Do not install another NAD model’s USB driver or reformat a drive to solve a computer-audio role mismatch.

Look for: The actual USB limitation is recorded without changing files.

Check the actual result

Is the cable attempting a computer-DAC role where the manual documents storage or service use?

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.
