Archive for the Apple audio board 820-2136, a 137 KB RAR file covering the daughterboard that handles audio connections. No revision or schematic number is given, so first confirm the 820 code silkscreened on the PCB. Such documentation lets a technician trace headphone or line jack detection, amplifier supply rails and the signal path toward the logic board when sound cuts out or a jack is not detected. Open it with WinRAR or 7-Zip and verify the included sheets match your hardware before replacing parts.
