More experimentation with ES3811 codec with on-board mic that's present on the Espressif ESP32-P4 EV board and the Waveshare ESP32-P4 Nano boards.
Seems more reliable for auto level control of the onboard mic, not causing random weirdness now.
Not tested in extremely loud venues yet, but seems fine at "home stereo not hurting your ears" volumes, and also fairly quiet volumes.
Pins for the Expressif P4 EV board and the Waveshare P4 nano board are both the same:
Type = ES8311
SD = 11
WS = 10
SCK = 12
MCLK = 13
SDA = 7
SCL = 8
I tested a lot of settings and this seems like a good starting point:
Squelch = 2 to 5 (tune to the point a quiet room shows no response)
Gain = 1
AGC = Normal
Mic Quality = Average
Profile = INMP441 (or the big/small speakers INMP441 variants depending on your environment)
