Sound first:

Nothing. Speaker isn't torn up, it's connected, not unplugged or chewed on wires. No wires off the volume control. ARI replaced with a known good one. I still have to go through and check that the speaker and volume control are good, but assuming they are, any common sound issues with Asteroids I should be aware of?

Testing with a known-good monitor, I get the following video:



I pulled a mud dauber nest off the X/Y section, and I need to go over it again to see if there is anything left there that might be causing an issue, but does this look like DAC's? Pots? Something else entirely?
 
sound pot is notorious for getting gummed up, so to speak. usually fixed by working it back and forth throughout it's range.

I assume you mean the one inside the door. I turned it full range many times, and not even a little static. My first step will be to hook up other audio at the lines coming from the AR1 to verify all the wiring, volume control and speaker are good. Then I'll check from the pcb to the AR1, then I'll get my audio probe out and figure out what's up...
 
Looks like it's resetting. You might not get any sound with a constant reset. Try the watchdog yet?

No, it's not resetting. I can start a game and see it play. Putting it into test mode looks the same way, but no beeping, even when I push buttons...
 
It looks like it might be a scaling issue - I'd poke around that section and related signals.

Best,

Bill
