Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Known working Universal Control monitor mix plus an unintended DAW input-monitor return.
Connection scope: USB audio. Symptom: Sound and picture are out of sync.
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
Are the same live input signals audible through both Universal Control and DAW software monitoring?
Recorded-track playback or an acoustic echo is a different issue.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Is the direct Universal Control mix already audible and the intended monitor path?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-1
Is the direct Universal Control mix already audible and the intended monitor path?
Do not remove a performer sole working monitor feed.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Can the session pause before changing its DAW input-monitor control?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-2
Can the session pause before changing its DAW input-monitor control?
This removes DAW-monitored effects for that live input; preserve the old setting.
Look for: Confirm the stated setup or observation. Unknown stops safely.
- If Yes / confirmed → Disable software input monitoring for that live input using the DAW documented control
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-3
Disable software input monitoring for that live input using the DAW documented control
Do not mute recorded-track playback or the working Universal Control mix.
Look for: Perform only the stated operation and confirm whether it was possible.
- If Yes / confirmed → Is the delayed duplicate gone while the intended direct monitor remains audible?
- If No / cannot confirm → Stop and retain the actual observations
- If I do not know / cannot check → A required fact is unknown

step-4
Is the delayed duplicate gone while the intended direct monitor remains audible?
This does not promise zero end-to-end latency or change a recorded take.
Look for: Confirm the stated setup or observation. Unknown stops safely.
