Thanks BuddyCasino!

At first blush that looks like what I'm seeing - just the channels reversed. So, either a) there's some sort of bug/problem in HW or b) there's a problem in the code and/or my understanding. I suspect it's a)...

Unfortunately, I think the bigger problem is this forum - "Discussion Forum -> Report Bugs" category. It doesn't seem to get much/any love or visibility.

So, I've got a couple things I'm gonna try to get to the bottom of this:
  1. take the microphones out of the equation by using a second ESP32 to generate the data
  2. Create a new post in the General forum.

Could be DMA word alignment issue?

Possibly, but it seems more bit-level - like bits are shifted and possibly repeated.
