Follow these checks in Audio Fix →

When this guide applies

Exact S.M.S.L C200. Original C200 supported optical media intermittently loses lock. Front headphones are the only used output and DPLL is positively below 9. This is an input-tolerance comparison, not a hardware diagnosis.

Connection scope: Optical digital audio. Symptom: Audio keeps cutting out.

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

Original C200 supported optical media intermittently loses lock. Front headphones are the only used output and DPLL is positively below 9. This is an input-tolerance comparison, not a hardware diagnosis.

Look for: Confirm this exact setup and observation before continuing.

If Yes, I confirm → Accept temporary optical interruption?
If No / my setup differs → Continue with source and model support
If I cannot confirm → More information is required

Possible result

More information is required

An unknown state is not a diagnosis. Record the last visible indication and consult the exact model instructions.

insufficient data

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

Possible result

Continue with source and model support

Keep the source, connection and last observation. Do not reset, open equipment or change full-scale output 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
