Grove_sound_sensor.py not working

So my program is getting hung up on at the line,

sensor_value = grovepi.analogRead(sound_sensor)

My firmware is up to date, and I’ve triple checked that its plugged into the right port.

Im not sure what the issue is, but would appreciate some help!

Hi Brian,

Could you add this line just after importing the library to see if it helps?

grovepi.set_bus(“RPI_1”)
