Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Known prepared safe mix; headphones currently assigned a different 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
Is the intended mix already prepared with safe levels?
Do not overwrite or invent a performer mix.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → May the headphone assignment be replaced while playback is stopped?

step-1
May the headphone assignment be replaced while playback is stopped?
One output receives only one mix; assigning this one overwrites the previous headphone feed. Record the old assignment.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Select the intended Mix in Focusrite Control 2
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

Select the intended Mix in Focusrite Control 2
Verify its name and sources before routing.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Open the pencil beside Routed to and select Headphones
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Open the pencil beside Routed to and select Headphones
Keep unrelated speaker/line-output destinations unchanged.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Does the intended mix now reach headphones at a gently raised level?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Does the intended mix now reach headphones at a gently raised level?
A saved route is not proof that its sources have signal.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
