Behringer X32 Compact

Compare actual input source assignments before assuming hardware damage.

1. Record whether the channel receives Local, AES50 or card audio.
2. Try one agreed local source on a protected path. If local input remains absent while other paths work, document it for service; do not open the console.
3. If the same source/cable works on an agreed spare input, compare the two channel assignments before service. Verify at the intended bus and destination; repeated failure on an isolated known-good path warrants support, not an internal repair attempt.

A processing output and a physical connector are different stages.

1. Trace bus to output assignment, then to AES50 transmit channels and rack outlet.
2. A virtual-output marker alone does not prove a fault. Compare one destination without copying another show’s full routing.
3. If the bus has signal but the selected AES50 transmission does not, the missing assignment precedes the rack connector. Correct only the agreed mapping and verify the exact outlet at protected level; if still silent, retain bus/transmit/outlet observations for support.

Installed expansion-card audio and top USB recording are separate paths.

1. Identify the card and computer device before checking card input/output routing.
2. Compare clock, source and destination. Preserve the live routing and test outside program; no generic firmware update.
3. If computer playback reaches a channel but recording does not, inspect the card’s transmit assignment separately. Verify one playback and one recording path without creating a return loop; unresolved device detection requires the exact card, OS, driver and clock record for support.
