these thing are finicky and sensitive, dialing them in is a challenge but that is the fun of it

Well chat Gpt fixed the example code and it runs fine on a replacement unit, I want to hook up a small amp to drive a bigger speaker on it next. 

the only other question is there a way to improve the MIcs on it?

I also could not get one of the sample codes to compile?
