Is there no sound when powered on? Or is there no sound when operating the lcd?

Same here. I replaced the buzzer with a piezo speaker, still terrible sound. The speaker signal is very disturbed(oscilloscope),there is no frequentie signal visible, just noise, maybe a timer problem?

Is there no sound when powered on? Or is there no sound when operating the lcd? "The speaker signal is very disturbed" I use M300 command from pronterface also. It seems i2c chain is not sutable for piezo type. But no way to turn it off and turn on buzzer type.
