Macintosh Mini - (yet another) Maclock conversion project

[wells]

I noticed a trim pot on the Adafruit sound module. I think it’s a gain adjustment but I wonder if adjusting it would have any effect on the digital noise it’s picking up and amplifying.

If the gain is too high, you'll likely hear noise. If lowering the gain solves the problem (and sound is still audible) then you should be set.

I was having trouble finding the description of what the buttons are supposed to do. The left one for me chimes and resets the emu. I can’t get it to do more than that. I thought a long press or a double tap exits to command prompt. Maybe that’s the right button which does nothing for me. Are these commands editable?

Buttons are configurable, see here in the docs.
