Compatibility & preservation
Do not assume the separately labeled mic, Hi-Z, line, headphone and S/PDIF paths share the same gain or channel mapping. Phantom power applies to the microphone input; check levels before connecting equipment.
- Photograph the card label, PCB revision, rear connectors and included breakout cables before service.
- Retain the exact working driver, firmware, operating-system version, clock and routing configuration.
- Confirm lane wiring, bracket clearance, channel map and external converter/network compatibility; connector fit alone is not a compatibility guarantee.
