I got lost too, I'm still not sure I've been found .
Basically it mixes the PWM stereo signal and then amplifies it using "half" of the PAM8302A (and half of the stereo pot. which can be replaced by a mono pot.)
Please don't start another endless debate about the audio, at least not in this thread. This works reasonably well, at least for the speaker I'm using, and it is what is going on the PCB. If someone wants to do differently then there will be opportunity to play after I have "released" it.
