Goal / when to use

IDFM does not list a device, UDP looks broken, or a firmware update fails. Match the symptom below.

Device missing from the list

Symptoms

DEVICES stays empty or omits a known amp.

Steps

Confirm PC and amp share the same L2 segment if you expect UDP discovery.
Check UDP STATUS — see Install.
Windows: use HELP → FAQ actions to re-apply firewall allow rules for IDFM.
If you know the IP, use + → add by IP.
If the amp is on another routed subnet, use subnet scan — broadcast will not cross the router.
Confirm only one IDFM instance is running.

Expected result

The amp appears via UDP or as a manually added / scanned device.

Goal / when to use

Something does not connect, discover, sync, or route audio. Work through the matching section below.

Out of Sync

Symptoms

Floating OUT OF SYNC alert in the UI
Device SYNC indicator not clean
Levels or EQ on the amp do not match Maxx Remote

Why it happens

Maxx Remote owns linked channels (Remote → device). Edits in Maxx Control, front-panel/other tools, or failed partial writes create differences. Maxx Remote detects them on periodic check-in.
