My question to the hard-core amiga hardware people here: If the voltage is messed up BEFORE it gets to the LM880, what's my next option? What components should I start looking at to replace?
Check the main motherboard power connector. My A4000 sound problems were caused by one of the ground pins getting pushed out of the connector and not making contact with the motherboard. I believe the power connector on the A4000 is six pins. You have +5, +12 and -12 volt supplies. Each supply has it's own ground pin (I think?) and the ground pin for the -12 volt on my connector got pushed out the back side of the connector coming from the power supply. When I pushed that back in, everything came back to normal for audio from my machine.
