Hello,
On RPI3, kernel Linux rpi196 4.9.58-v7+ #1046 SMP Tue Oct 24 17:07:15 BST 2017 armv7l GNU/Linux, raspbian stretch (9). I'm following https://learn.adafruit.com/adafruit-i2s-mems-microphone-breakout/raspberry-pi-wiring-and-test and can record my voice via 2 i2s mic as stereo. But I can't control the MIC volume follows the tutorial.
