I’m using adafruit I2S MEMS (SPH0645LM4H) microphone with Jetson Nano. Conneted as follows using jumper wires(20cm)
LRC → 35
DOUT–> 38
BCLK–>12
GND → GND
3V → 3V3

That works fine.

But when I extend the cable to nearly 1.5 meter by adding a new 1.2m cable to the same jumber wire. The mic doesn’t work. Although I tried with different wires including cat 06 cable, it doesn’t work.

That could happen because of the longer cable.
