Follow these checks in Audio Fix →

When this guide applies

Headphone silence with known host playback; no microphone or USB changes.

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

step-0

Is intended playback already reaching the interface output path?

If source routing is unknown, this plug check cannot establish it.

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