Using the DAC outputs make sense. I'll make that change.
I was starting to realize that the problem was with the internal regulator and am planning on rewiring to run independently from a external regulator powered by the battery.
I realize the speakers are small. they're just for testing. I'm planning on replacing them with larger speakers when I have things working. I want to make a flying ghost Halloween prop and intend to imbed the project in the ghost's head. That's what the hall effect sensor is for, to trigger the sounds when the head starts moving.
Thanks for your input, it helps.
