When this guide applies

Headphone path known working, but currently auditioning another mix.

Connection scope: USB 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 intended Main 1/2 mix meter and play normally elsewhere?

An absent source signal is not a headphone-source selection problem.

Look for: Confirm the stated setup or observation. Unknown stops safely.
